[installer] Clean up dead metrics
Remove LZMA metrics that are no longer recorded. Also mark others as
never expiring since they are general installer-health metrics and
update ownership.

OBSOLETE_HISTOGRAM[Setup.Install.LzmaUnPackStatus_ChromeArchivePatch]=All recording removed in r1522199.

Chromium 142 broke delta updates on Windows. This commit fixes them by
reverting upstream commits 13ca199c and a4d120da with a few patches,
vendored code and chromium_src overrides. The changes should affect the
browser Windows installer only, and not the Omaha update client.
