TinyGL: Bug fixes. info3ds, info3ds_u, vox_tgl: Related changes (#210)

Browse Source 
TinyGL:
- The `depth` parameter in the `glClearDepth` function is now `qword` instead of `dword`.
- Fixed bug with z-buffer (the edges were cut off incorrectly, the coordinates in it were from 0 to 1, but should be from -1 to 1)
- Optimized array functions: `glDrawArrays`, `glDrawElements`

info3ds, info3ds_u, vox_tgl:
- Removed unnecessary operations after fixing a bug with the z-buffer.
