tu: Disable bicubic filtering for compressed formats

Qualcomm also disables this, and this will fix some tests added to vulkan CTS 1.2.8 blitting from compressed textures with bicubic filtering once https://gerrit.khronos.org/c/vk-gl-cts/+/8682 lands.

I tried making the test to make the source image use the uncompressed view that the test expects directly, and some of the tests do pass while others still fail. So it seems there's a combination of precision issues with the tests and what's probably differences in Qualcomm and CTS's implementation of compression. But given that we don't have the ability to look into the implementation, we'll just follow Qualcomm's lead.
