Fix fuzzer-discovered assertion with texture2d parameters.
The Metal code generator would assert if you try to `writeType` on a
texture type, because we don't know the access type to pass (read,
write or both). Places in the code which can support textures need to
call `writeTextureType` instead.
Function parameters weren't considered here, so they tripped the
assert. We now have `writeParameterType` which can be used. For now,
we don't have a good way of setting access type on texture params,
so you will get the default access type (sampleable, no read/write).
In the future we can add `readonly` and `writeonly` modifiers to
pass access information, like GLSL.
