panvk: check for texture-compression support

We currently just assume that textureCompressionETC2 and
textureCompressionASTC_LDR are always supported. And while that's true
for all the G52s, G610s abd G310s we've seen out in the wild, it's not
guaranteed to be true. An SoC vendor might disable support for one of
these formats.

So let's check properly, just for good measure.
