qapi qga: Elide redundant has_FOO in generated C
The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with. Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step. This is the step for qga/qapi-schema.json.
Said commit explains the transformation in more detail. The invariant
violations mentioned there do not occur here.
