Jim Mussared d040478d8a 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.
