BasicNameofTestSuite: Split the multi-scenario facts

[YYDan]

Description

BasicNameofTestSuite was never covered by the summer 2024 refactor campaign. It is small — 9 asserts in 4 facts across 41 lines — but every fact bundles two or three independent checks:

Fact	Asserts
nameof_macro_test	3 (real-valued macro, string-valued macro, tab-prefixed macro)
nameof_enum_test	2
nameof_global_test	2
nameof_localvar_test	2

Each assert is a fully independent check of nameof() against a different declaration kind, so this splits cleanly with no shared setup to duplicate.

Note the assert messages in nameof_localvar_test already carry #7 and #8 prefixes. Per convention these are preserved verbatim even though they will no longer match the new fact numbers.

Target: 9 facts.

BasicNameofTestSuite

Steps To The Task

• Split all four facts into one fact per assert, named <original_name> #N
• Leave the existing macro, enum and global declarations at file scope where they are
• Preserve the existing #7 / #8 assert message prefixes verbatim
• Add section comment headers per declaration kind
• Confirm the total assert count is unchanged (9) and that no fact name is duplicated
• Run the suite on VM and YYC and confirm the same set of checks pass as before
