[llvm] [AsmPrinter][ELF] Support profile-guided section prefix for jump tables' (read-only) data sections (PR #122215)

[Mingming Liu via llvm-commits]

The updated PR also generates `.rodata.<suffix>.` (with a trailing dot after `<suffix>`) when `-ffunction-sections` is false, for consistency with existing code (which sets `HasPrefix` for linker's disambiguation between `.text.<section-prefix>.` and `.text.<function>`).

PTAL, thanks!
