Dave Lee 1250a1db1a [lldb] Update dwim-print to support limited variable expression paths (#117452) ...

`frame variable` supports nested variable access, which the API calls "variable
expression paths". This change updates `dwim-print` to support a subset of supported
variable expression paths.

Consider the expression `a->b`. In C++, the arrow operator can be overloaded, and where
that is the case, expression evaluation must be used to evaluate it, not frame variable.
Likewise, the subscript operator can be overloaded.

To avoid those cases, this change introduces a limited support for variable expression
paths. Use of the dot operator is allowed.

Additionally, this change allows `dwim-print` to directly access children of `this` and
`self` (see AllowDirectIVarAccess). This functionality is also provided by the same
`GetValueForVariableExpressionPath` method.
