This commit adds required files into the offload build closure,
which means adding RT_API_ATTRS and other markers.
The implementation does not work for CUDA yet, because of
std::variant,swap,reverse usage. These issues will be resolved
separately (e.g. by using libcudacxx header files).
This is a simplified implementation of std::optional that can be used
in the offload builds for the device code. The methods are properly
marked with RT_API_ATTRS so that the device compilation succedes.

An Ew.0(Ee) or Ew.0(Ee) output edit descriptor with a scale factor of
zero is an error condition, unless the output edit descriptor was
originally Gw.0(Ee), list-directed, or just E0/D0 with no .d part.
Fixes https://github.com/llvm/llvm-project/issues/78390.
In Fortran, a format automatically repeats, with a line break, until all
the data items of a data transfer statement have been consumed. PRINT
"(3I4)", 1, 2, 3, 4, 5, 6 prints two lines, for example, three values
each.
When there are nested parentheses in a format, the rightmost set of
parentheses at the top level are used for automatic repetition. PRINT
"(I4,2(I4))" 1, 2, 3, 4, 5, 6, 7 print three lines, with three values on
the first and two each on the later ones.
Fix a bug in format interpretation that causes the detection of the
"rightmost" set of parentheses to take place on each pass, leading to
problems when parentheses are even further nested.
A fairly recent introduction of runtime I/O APIs called OutputDerivedType()
and InputDerivedType() didn't cover NAMELIST I/O's need to access
non-type-bound generic interfaces for user-defined derived type I/O
when those generic interfaces are defined in some scope other than the
one that defines the derived type.
The patch adds a new data structure shared between lowering
and the runtime that can represent all of the cases that can
arise with non-type-bound defined I/O. It can represent
scopes in which non-type-bound defined I/O generic interfaces
are inaccessible, too, due to IMPORT statements.
The data structure is now an operand to OutputDerivedType() and
InputDerivedType() as well as a data member in the NamelistGroup
structure.

A handful of I/O statements (OPEN, CLOSE, positioning) are not allowed
on units during child I/O; catch violations and report errors.
Also finesse error handling during FORMAT runtime parsing of DT
derived type edit descriptors, and ensure that formatted child
I/O is nonadvancing.

A character array can be used as a format in an I/O data transfer
statement, with the interpretation that its elements are concatenated
in element order to constitute the format.
Support in the runtime with an extra optional descriptor argument
to six I/O API calls; support in semantics by removing an earlier
check for a simply contiguous array presented as a format.
Some work needs to be done in lowering to pass a character array
descriptor to the I/O runtime API when present

Allow internal I/O to support non-default kinds of CHARACTER.
The I/O runtime design anticipated this standard feature, but
this patch is somewhat larger than I thought it would be because
many code sites had to have assumptions about units (characters
vs. bytes) brought into harmony, and some encoding utilities
had to be pulled out of IoStatementState and templatized into
their own new header file so that they are available to formatted
output code without having to "thread" an IoStatementState reference
through many call chains.

Since dynamic FORMAT strings usually come from blank-padded fixed-length
CHARACTER variables, trim leading and trailing blanks from them when they
are echoed to error messages for better readability.

When an I/O data transfer statement uses an ASSIGN'ed FORMAT that
has not been ASSIGN'ed to a FORMAT statement, the runtime receives
a zero-length format string. Distinguish this case from the general
error message about missing parentheses.

User-defined derived type editing in formatted I/O wasn't
working with repeat counts; e.g., "2DT(10)". The solution required
some code to be moved from GetNextDataEdit() to CueUpNextDataEdit() so
that a stack entry for a nonparenthesized repeated data edit
descriptor would work correctly -- all other data edit descriptors
are capable of dealing with repetition in their callees, so the bug
hadn't been exposed before.
Debugging this problem led to some improvements in error messages
for bad format strings, and those changes have been retained; also,
a dead member function was discovered and expunged.

NAMELIST array input does not need to fully define an array.
If another input item begins after at least one element,
it ends input into the array and the remaining items are
not modified.
The tricky part of supporting this feature is that it's not
always easy to determine whether the next non-blank thing in
the input is a value or the next item's name, esp. in the case
of logical data where T and F can be names. E.g.,
&group logicalArray = t f f t
= 1 /
should read three elements into "logicalArray" and then read
an integer or real variable named "t".
So the I/O runtime has to do some look-ahead to determine whether
the next thing in the input is a name followed by '=', '(', or '%'.
Since the '=' may be on a later record, possibly with intervening
NAMELIST comments, the runtime has to support a general form of
saving and restoring its current position. The infrastructure
in the I/O runtime already has to support repositioning for
list-directed repetition, even on non-positionable input sources
like terminals and sockets; this patch adds an internal RAII API
to make it easier to save a position and then do arbitrary
look-ahead.

Non-advancing I/O was failing; ExternalFileUnit was losing
track of what writes had been committed to the file. Fixed.
Also, support the common extension of $ and \ in a FORMAT
as being equivalent to ADVANCE=NO.

With derived type description tables now available to the
runtime library, it is possible to implement the concept
of "child" I/O statements in the runtime and use them to
convert instances of derived type I/O data transfers into
calls to user-defined subroutines when they have been specified
for a type. (See Fortran 2018, subclauses 12.6.4.8 & 13.7.6).
- Support formatted, list-directed, and NAMELIST
transfers to internal parent units; support these, and unformatted
transfers, for external parent units.
- Support nested child defined derived type I/O.
- Parse DT'foo'(v-list) FORMAT data edit descriptors and passes
their strings &/or v-list values as arguments to the defined
formatted I/O routines.
- Fix problems with this feature encountered in semantics and
FORMAT valiation during development and end-to-end testing.
- Convert typeInfo::SpecialBinding from a struct to a class
after adding a member function.
