php-ts-mode' depends on mhtml-ts-mode' instead of JS,CSS and HTML

The direct dependence on js-ts-mode, css-ts-mode and html-ts-mode
has now been replaced by 'mhtml-ts-mode'.
Additional benefits are:
1. Imenu now exposes symbols for all of all languages,
2. navigation now works correctly for all languages,
3. outline works for all languages.

Additional new features are:
1. indentation of PHP in mixed buffers with HTML now works much
better and allows three different behaviors, an option allows you to
choose the behavior.
2. a new feature shows where PHP ini files are both locally and
remotely, if the buffer is associated with a remote PHP file.

* etc/NEWS: Mention the rationale for those changes, the new command,
and the new options.
* lisp/textmodes/mhtml-ts-mode.el (mhtml-ts-mode--range-settings): New
variable that store range settings.

'php-ts-mode--comment-current-plist'.
