General: remove backwards-compatible code for versions < 6.5 (#38386)

Now that we require WordPress 6.5, we can remove any
backwards-compatibility checks for folks that run WP 6.4.

I also cleaned up some older stuff while I was looking.

* js-packages/components: Remove a deprecation kept for 6.4 compat.
* packages/jetpack-mu-wpcom: Simplify a test.
* plugins/jetpack: Remove unnecessary `version_compare()` calls, assume
  WP 6.5+.
* plugins/jetpack: Remove a check for us being Jetpack >=5.3.
* plugins/jetpack: Remove some code checking for `JSON_BIGINT_AS_STRING`
  support, which was added in PHP 5.4.
* plugins/jetpack: Address some `@todo` comments calling for action once
  WP 6.5 is the minimum.
* plugins/jetpack: Remove support code for a feature removed in #33782
* plugins/wpcomsh: Remove unnecessary `version_compare()` calls, assume
  WP 6.5+.
* plugins/wpcomsh: Remove some checks for old Jetpack versions.
* plugins/wpcomsh: Remove a polyfill for WordPress before 5.4.
* cli: Update some code for node 20.1+.
