LibWeb: Skip large stacking context in gpu painter only if it allocates

Skipping all stacking contexts with a size larger than 10000px in one
dimension was a mistake because it also affects pages that are simply
tall due to having a lot of content. Instead, we only need to skip if
the stacking context requires the allocation of a framebuffer that
could possibly fail.

Fixes SerenityOS#23397
