Stdlib: locale_filter_matches() JIT lowering via VmLocale helper (#32119)

[PurHur]

Summary

• Replace locale_filter_matches() JIT RuntimeException (JIT lowering not implemented; use VM) with prefix-filter lowering that matches VM/VmLocale::filterMatches() (php-src ext/intl/locale/locale_methods.c).
• Compile-time fold when languageTag/locale/canonicalize are literals; otherwise NestedJIT LocaleFilterMatchesJitHelper::filterMatchesArgv() via __phpc_jit_locale_filter_matches (int 0/1 → i1, peer #31966).
• Same helper for Locale::filterMatches() (functionProxies['locale::filtermatches']). php-src-strict; no php-compiler-strict shortcut.

Closes #32119

Test plan

• ./script/phpunit.sh --filter 'LocaleFilterMatchesJitShrinkTest|LocaleFilterMatchesJitCompileTest|LocaleFilterMatchesJit32119'
  • OK (7 tests, 27 assertions) — VM + JIT .phpt result path (ordinary, named, vars, canonicalize keyword/grandfathered, unknown $langtag)
• ./script/docker-exec.sh -- bash -lc 'php test/repro/issue_32119_locale_filter_matches_jit.php'
  • filter_pos=true / filter_named=true / filter_vars=true / kw_f=0 / kw_t=1
• php script/bootstrap-inventory.php --check → OK 7586/7586
• Host AOT of advertised locale_filter_matches (this image: extension_loaded('intl')=0; AOT fixture SKIPIFs)
