After landing bug 1726275 and an initial period of testing for macOS, enable for Windows and Linux.

This looks green on Try, so should be good to land soon: https://treeherder.mozilla.org/jobs?repo=try&revision=3026ba7d4a76cc23b5780272ac2d430c6726e2aa

Aiming for Firefox 98 to land this.

TODO:

• Rename audioipc2 crates back to audioipc
• Merge macos branch to master
• Refresh WIP patch to include above

The code removal will be done in bug https://bugzilla.mozilla.org/show_bug.cgi?id=1697845. This bug will track preffing on v2 for Windows/Linux by default once bug 1748160 lands.

Backed out for causing dt failures on browser_devtools-interrupted.js

Bug 1750810 will revert this change for Linux in Nightly 98 until the existing issues are resolved. Windows will remain enabled as we've had no reports of issues and there are zero Windows crashes showing up on crash-stats.
