arb_shading_language_420pack: Add multiple layout qualifiers in a single output declaration tests

This adds tests to check that all layout-qualifier-ids are taken into
account when spread across multiple layout-qualifiers for a single
global output declaration.

The tests check that this works for value and non-value
layout-qualifier-ids.

From the ARB_shading_language_420pack spec:

    "More than one layout qualifier may appear in a single declaration."
