feat(php): switch the PHP language level from the status bar (#1371)

With a PHP file focused, the status bar shows the PHP level Intelephense
checks against (`PHP 7.4`); the tooltip says where it comes from (the
settings, config.platform.php or require.php). Clicking it opens Auto (with
the composer.json version) and 5.6 to 8.5; picking one writes the same
project setting as Settings › Languages & Frameworks › PHP, so diagnostics
follow without reopening the project. The widget is hidden for other files.
For a file of a linked workspace project, the level comes from that
project's settings and the choices are disabled. The menu is also the
action "PHP Language Level".

Closes #1091
