Lazily redo RLE encoding
...
Also stop lying about the RLE encoding state, which causes crashes if we do RLE blit operations while the surface is locked.

Enable RLE more often in the software renderer
...
We don't need to aggressively disable RLE acceleration anymore because the original pixels remain available for operations that aren't supported by the RLE blitter.

D3D12 GPU: Prevent reading out of bounds when uploading textures.
...
When the upload needs realignment, a new buffer is created to do the
upload, and the source data is copied to the new buffer. This commit
fixes the issue where the memcopy can read off the end of the source
buffer since it is reading based on destination pitch instead of source
pitch.
