 Upgrade/Install: Remove parsing of `readme.txt` files for plugin or theme
 requirements.

 This affects:
 * `validate_plugin_requirements()`
 * `validate_theme_requirements()`

 Historically, the `Requires PHP` header was introduced in #meta2952 for
 the Plugin Directory first, so at the time it made sense to have it
 defined in the same place as `Requires at least`, which only existed in
 `readme.txt`.

 Since parsing of PHP and WordPress requirements was later added to
 WordPress core, the core should retrieve all the necessary data from the
 main plugin or theme file and not from `readme.txt`, which only contains
 the data meant for the Plugin or Theme Directory.

 The recommended place for `Requires PHP` and `Requires at least` headers
 is as follows:
 * The plugin's main PHP file
 * The theme's `style.css` file

 The place for the `Tested up to` header remains in `readme.txt` for the
 time being, as it's not used by WordPress core.

 Follow-up to [44978], [45546], [47573], [47574], [meta5841], [meta9050].

 Fixes #48520. See #48515, #meta2952, #meta4514, #meta4621.
