Draft: Reenabling bool tests

[tdavidovicNV]

• Fixed a bug where call to _set_array would get type from reflection rather than ndarray
• Removed unnecessary striding in _set_matrix in BufferElementCursor.
• Added float4x3 tests to test_buffer_cursor
• Added faster memcpy codepath to shader_cursor when src and dst layout matches.
• Removed get_scalar_type_size as type sizes and strides need are not static (need to rely on reflection system anyway).
• Added handling for setting scalars, vectors and arrays of bools based on the backend reflection types.
• Added tests for bool2 buffers.
• Enabled bool cursor tests for CUDA and Metal.
• Added workaround for Slang CUDA-backend issue Reflection system misreports boolX layout on CUDA slang#7441
• Added tests for bool2 reflection data, to catch when Reflection system misreports boolX layout on CUDA slang#7441 is resolved.

This cannot be re-enabled in the current state, due to the CUDA backend having unpredictable behaviors.
