[video_core] fix std::bitset<> dirty tracker OOB, fix slightly wrong index format estimate (#4006)

Browse Source 
u8 may have been 0xff, (aka. 255), but bitset was only 255 elements, so doing bitset[255] is technically OOB

additionally the max size estimate for index formats was not correct, there can be up to 256 elements with a u8 format index, not just 255
