Trac ticket: #65819

What

Adds a dedicated PHPUnit class for wp_get_ext_types(), covering default type keys, representative extensions, and the ext2type filter.

Test-only; no production code changes.

Why

wp_get_ext_types() had no direct @covers coverage. Small helper coverage fits the #65819 test cleanup track.

How

Add tests/phpunit/tests/functions/wpGetExtTypes.php with @covers ::wp_get_ext_types.

Testing Instructions

  1. npm run test:php -- --filter Tests_Functions_WpGetExtTypes
  2. npm run test:php -- --filter Tests_Functions_WpGetExtTypes -c tests/phpunit/multisite.xml
  3. npm run test:php -- --filter Tests_Functions_WpGetExtTypes --order-by=random
  4. npm run test:php -- --group functions

Literal extension membership catches map deletion that the existing self-derived extension loop misses. Existing filter coverage makes the added filter method optional duplication.

Local randomized single-site and multisite checks passed with related existing tests: 51 tests, 319 assertions across this five-PR batch (seed 15273). PHPCS passed.

Optional: Fold literal memberships into the existing test and omit the repeated filter exercise and full key-list assertion.
