  Log Message:
  -----------
  [flang] Enumeration Type: (PR 1/5) Foundation types + Parser (#192651)

This PR creates the concept of an ENUMERATION TYPE from the Fortran 2023
Standard. It is implemented as a special case of a Derived Type
internally to the compiler. It adds the parse/unparse support. The
compiler will be able to recognize the syntax of an ENUMERATION TYPE and
report to users that the feature is not yet implemented.

It is the 1st of 5 stacked PRs.

AI Usage Disclosure: AI tools (Claude Opus 4.6) were used to assist with
implementation of this feature and test code generation. I have
reviewed, modified, and tested all AI-generated code.
