Update Mono to 5.10.1.47

This brings a more modern Mono release to the ports tree. After
discussions with others in the Mono community I targeted the mono
5.10.1.47 release which is the latest release in the "Visual Studio"
release channel. This is considered to be the most stable and widely
tested, which makes it a good candidate for us. We may upgrade to 5.12
after additional testing or introduce another Mono package for users who
require testing against a newer release; this has yet to be determined.

- Build from official release tarballs
- Now include BoringSSL per upstream guidelines [1]
- Remove ACCEPTANCE_TESTS, not being updated by upstream
- No long require glib; Mono includes their own replacement
- USES=display:tests required for some tests
- Remove broken for armv6, armv7: file now available [2]
- Mark as LLD safe as mono changed how it handles TLS [3]
