Implement ResidentKeyRequirement

[relan]

Is your feature request related to a problem? Please describe.
org.microg.gms:play-services-fido does not have ResidentKeyRequirement. It's needed to replace com.google.android.gms:play-services-fido in Firefox. See the use in GeckoView.

Describe the solution you'd like
Add ResidentKeyRequirement and related stuff (including builder method).

Describe alternatives you've considered
Made a patch to remove ResidentKeyRequirement but didn't have a chance to test it:

This was added to the Play Services Fido API by Google earlier this year (along with a few other things) and thus isn't present in the implementation of microG yet. Will add soon.

Hi,
is it possible to have a compiled build of Firefox with org.microg.gms:play-services-fido to test?

[mar-v-in]

Nightly is also updated with those changes.

Good, thanks :)

GeckoView builds fine with org.microg.gms:play-services-fido compiled from 666361a. Thanks!
