Travis Support Arm SVE

- Updated distro to 20.04 focal aarch64-gcc-10.
  This is minimal version required by aarch64-gcc-10.
  SVE intrinsics would not compile without GCC >=10.
- x86 toolchains use official repo instead of ubuntu-toolchain-r/test.
  20.04 focal is not supported by that PPA at the moment.
- Add extra configuration-time options to .travis.yml.
- Add Arm SVE entry to .travis.yml.
