Pcbnew: Fix rotating bitmaps 

Fixes rotating bitmaps with "rotate counterclockwise",
"rotate clockwise" and "move exactly" commands.

Only rotation by 0, 90, 180 and 270 degrees is supported
for bitmaps. Other values are rounded to the nearest 90
degree multiple.

There is a different bug that this commit doesn't address,
which is that BITMAP_BASE::Rotate() got its CW/CCW logic
reversed ("m_image->Rotate( false )" should rotate CW, but
does not).

Fixes https://gitlab.com/kicad/code/kicad/issues/14197
