[llvm-readobj] - Add proper testing for the SHT_MIPS_ABIFLAGS section.

[grimar]

Summary

This rewrites the mips-abiflags.test to stop using recompiled objects,
adds testing for all missed bits and also adds two missing enum values
to lib/ObjectYAML, which are used in the new test.

[atanasyan]

LGTM

[MaskRay]

LGTM.
