  Fix blitframebuffer-test.html to use non-equivalent format for multisampled 
sRGB format mismatch test

Reviewed by Kimmo Kinnunen.

blitframebuffer-test.html was changed here: 
https://commits.webkit.org/267783@main, but those changes
were reverted in an unreviewed upstream import here: 
https://commits.webkit.org/270111@main.

This patch reintroduces the changes seen before the upstream import.

blit_framebuffer_multisampling_srgb() validates format mismatch detection for 
multisampled sRGB blits. It is expecting that
RGBA is not equivalent to sRGB. ANGLE treats them as equivalent, so the test 
fails. The fix is to use RGB8 in the test
instead because it is truly not equivalent.
