ext/zip: withhold extension_loaded/ZipArchive on reference profile (#18137)

[PurHur]

Summary

• Gate extension_loaded('zip'), ZipArchive, and zip_* procedural API behind CompilerVersion::supportsZip() (msgpack/brotli pattern) so the 8.4.0-dev reference harness matches Zend without ext/zip
• Register zip module under standard with logical zip extension name only when advertised; forward profile enables via PHP_COMPILER_PROFILE=8.4
• Add repro + compliance guards; skip functional zip PHPTs on reference profile in VMTest/JITTest

php-src reference

• ext/zip/php_zip.c — module init registers extension + classes together
• ext/standard/info.c — extension_loaded() reflects loaded modules only

Verification

./script/docker-exec.sh -- bash -lc 'PHP_COMPILER_PROFILE=8.4 php bin/vm.php -r "echo extension_loaded(\"zip\")?1:0; echo \" \"; echo class_exists(\"ZipArchive\",false)?1:0; echo \" \"; echo function_exists(\"zip_open\")?1:0;"'
# 1 1 1

./script/docker-exec.sh -- bash -lc 'vendor/bin/phpunit test/compliance/VMTest.php --filter extension_loaded_zip'
# OK (2 tests, 2 assertions)
