tu/kgsl: Better detection of sparse support

Browse source 
Apparently a device can support KGSL_MEMFLAGS_VBO but not
IOCTL_KGSL_GPUMEM_BIND_RANGES or IOCTL_KGSL_GPU_AUX_COMMAND.

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/15006
Fixes: 71ef46717c ("tu/kgsl: Add support for sparse binding")
