support/testing: test_edk2: add a few build tests

Some EDK II configurations have complex dependencies on several packages
and additional build options; build tests help keeping track of those
more easily.

Factorize some code common to all the build tests into a new
TestEdk2BuildBase class, which defines a base configuration and a method
to assert that binaries do indeed exist after the build.

While at it, add myself in DEVELOPERS.
