Remove the TestContextFactory, always use NullDraw GL for unit tests.

All unit tests suites are now opted into using real NullDraw GL
contexts instead of fake "test contexts". So remove the code to
create test contexts.

Removes the --disable-test-compositor flag as this does nothing
now that no tests use test contexts.
