Travis-CI: Use new Ubuntu 20.04 as base, streamline and document

Simplify Travis-CI file and extend inline comments. Upgrade to using Ubuntu 20.04 (Focal) as the baseline distro version now that Travis-CI has made it available. Drop Xenial and all the excess repositories Xenial needed. Now we only Focal and one Bionic build to keep things simple and streamlined. Keep GCC-7/Clang-7 as the older compiler, and start using GCC-10 and Clang-10 as the newer compiler. Assume that if both of them build OK, than the intermediate versions would be OK as well. Print 'apt-cache policy' to make it transparent in build logs what repositories was used for build dependencies. Remove temporary workaround from homebrew install step as Travis-CI has fixed the original issue. Revert ignoring results form build that previously failed on the test main.thread_pool_info as MDEV-20372 is not fixed. Keep arm64 failures ignored due to MDEV-23955. Allow failures for the test main.column_compression 'innodb' due to MDEV-23954 (already fixed, but not on 10.6 branch yet).
