Update indentation for PHP, JS, and TS (#251465)

* Update indentation for PHP, JS, and TS.

Addresses https://github.com/microsoft/vscode/issues/136592

- For PHP, auto-indent after `if`, `elseif`, `else if`, `while`, `for` and `foreach`. This also fixes an issue where hitting Enter on a blank line below a single line `if` (or other) results in an extra tab.
- For PHP, extra dot after `*/` and blank line.
- For JS/TS, auto-indent for `else` to be consistent with handling of `if` statements

* polish
