Update indentation for PHP, JS, and TS

[ssigwart]

Based on feedback in #136593 (comment).

@aiday-mar, as I mentioned in the linked PR, I wasn't super thrilled with doing it this way based on my thoughts in #43244 (comment) and #43244 (comment). However, I did some testing and VS Code will now unindent when { is pressed, which makes the original change to auto-indent still a change in expections, but something I can probably get used to. However, I noticed that else wasn't handle consistently in JS and TS, so I fixed those in here (I see that it was mentioned in #43244 (comment) too). Personally, I can probably remove my extension that reverted the original auto-indentation changes and adjust to the new indentation this PR introduces, but based on feedback from #43244, there might be some backlash when this gets merged.

Addresses #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 space after */ and blank line.
• For JS/TS, auto-indent for else to be consistent with handling of if statements

Testing

In the following PHP code, hit Enter on the last blank line, it will add a space in front of the new line.

/**
 * PHPDoc
 */

Similarly, if you have the following code and hit Enter on the blank line, it will add a tab in front of the new line.

if (1)
	1;

I also tested writing some if, else if, and else statements in PHP, JS, and TS.
