Mitchell Hentges d484895832 Bug 1748762: Update mach.ps1 to always support MozillaBuild 4.0 r=saschanaz
MozillaBuild 4.0 changed its `start-shell.bat` API for consumers that
want to run a command within it, while keeping their current terminal
active.

For a little bit, compatibility with `MACH_PS1_USE_MOZILLABUILD` will be
maintained, though the recent work in bug 1740123 should entirely
obsolete it. It's staying around //for now// so that regressions in
1740123 don't unnecessarily impede workflows.

However, `MACH_PS1_USE_MOZILLABUILD` has some serious drawbacks already
(can't have whitespace in arguments, can't pass braces to Mach, etc).
This patch still has these drawbacks, because they're tricky to solve.

In a couple months, once bug 1740123 has settled nicely, we'll remove
support for `MACH_PS1_USE_MOZILLABUILD`.
