Attachment: Bug 1910360 - use quinn-udp instead of NSPR for QUIC I/O on Nightly r=kershaw

https://phabricator.services.mozilla.com/D212959 adds optional support for QUIC
I/O via quinn-udp instead of NSPR. This is controlled via pref
network.http.http3.use_nspr_for_io. The default pref value was true, thus
not using quinn-udp, but NSPR as before.

This commit enables the use of quinn-udp on Firefox Nightly.

Summary from bug 1910594

• Prior to publishing, we sanity check [Fenix/Focus] startup Nightly on [ARMv64v8a/x86] on a mix of physical and emulated devices
• x86 Nightly Android startup was crashing with this preference enabled w/ seccomp prevented call to disallowed x86 system call 337
• Unfortunately I don't have symbolicated crash-stacks
• This should be reproducible on installing affected APKs (CI link) on an x86 emulator image on an x86 host and launching Fenix

Thank you Serban, Ryan and Aaron for the investigation and sorry for the trouble. I will take a look tomorrow.

Seems like recvmmsg is by default blocked by seccomp on Android x86.
