revert fix(video): handle invalid texture format in format lookup table

Return default pixel format for uninitialized texture descriptors
(format=0, components=0) instead of asserting. Prevents crashes when
texture cache encounters uninitialized texture data.

Fixes assertion failures in format_lookup_table.cpp:250.
