glsl: Track matrix layout of variables using two bits

Fixes gles3conform failures in:

ES3-CTS.shaders.uniform_block.random.nested_structs_arrays_instance_arrays.3
ES3-CTS.shaders.uniform_block.random.all_per_block_buffers.13

Causes gles3conform failures in:

ES3-CTS.shaders.uniform_block.random.all_per_block_buffers.9

This failure will be fixed shortly.

v2: Use without_array() instead of older predicates.

v3: s/GLSL_MATRIX_LAYOUT_DEFAULT/GLSL_MATRIX_LAYOUT_INHERITED/g
