GRSurface::Create() doesn't need to rely on caller specifying the buffer size, as it can compute that info based on the given args. This CL also uses `size_t` for all the parameters in GRSurface::Create(). Test: Run recovery_unit_test on marlin. Test: Build and boot into blueline recovery. `Run graphics test`. Test: Build and boot into blueline charger mode. Change-Id: Idec9381079196abf13553a475006fefcfca10950
