extmod/modframebuf: Validate FrameBuffer bounds against input buffer. This ensures that the buffer is large enough for the specified width, height, bits-per-pixel, and stride. Also makes the legacy FrameBuffer1 constructor re-use the FrameBuffer make_new to save some code size. Fixes issue #12562. This work was funded through GitHub Sponsors.

extmod/modframebuf: Fix FrameBuffer size check for stride corner-cases. This is a fix for issue #15944, and handles corner cases in the FrameBuffer code when using stride values where the last line's stride may extend past the end of the underlying buffer. This commit includes extra tests for these corner cases. For example a GS8 format FrameBuffer with a width of 8, height of 2 and stride of 10 should be able to fit into a buffer of size 18 (10 bytes for the first horizontal line, and 8 bytes for the second -- the full 10 bytes are not needed). Similarly a 1 by 9 FrameBuffer in MONO_VLSB format with a stride of 10 should be able to fit into a buffer of length 11 (10 bytes for the first 8 lines, and then one byte for the 9th line. Being able to do this is particularly important when cropping the corner of an existing FrameBuffer, either to copy a sprite or to clip drawing. Signed-off-by: Corran Webster <cwebster@unital.dev>
