jeanPerier a8db1fb9b5 [flang] update fir.coordinate_of to carry the fields (#127231) ...

This patch updates fir.coordinate_op to carry the field index as
attributes instead of relying on getting it from the fir.field_index
operations defining its operands.

The rational is that FIR currently has a few operations that require
DAGs to be preserved in order to be able to do code generation. This is
the case of fir.coordinate_op, which requires its fir.field operand
producer to be visible.
This makes IR transformation harder/brittle, so I want to update FIR to
get rid if this.

Codegen/printer/parser of fir.coordinate_of and many tests need to be
updated after this change.
