  -----------
  [DebugInfo][CodeView] Reuse enum tables in type dumpers (#202757)

Reuse the process-lifetime enum tables in `EnumTables.cpp` from
`TypeDumpVisitor` and `TypeRecordMapping` instead of emitting duplicate
`EnumEntry` arrays.

On Darwin arm64 Release, `llvm-readobj` decreases from 12,046,992 to
12,030,048 bytes (-16,944 bytes), with 599 fewer fixups

Work towards #202616
