ARM C++ build for Debian 11

[ankane]

Hi @Mizux and @lperron, hope things are good.

I wanted see if an ARM C++ build for Debian 11 could be added to the release process. This was manually done for v9.8 in #4007, but don't see one for v9.9.

(If not, no worries, but will remove support for it from the Ruby gem)

Will try to do it on Wednesday, forget my M1 at office ^^;

dev note: Debian 11 image should be aarch64 ready (may need to remove dotnet if microsoft don't provide a feed)
