v3dv: enable the logicOp feature

For us this is mostly handled in the compiler by a NIR lowering so
for the Vulkan driver we only need to make sure that we program our
shader key correctly from the pipeline state, which we were already
doing.

It doesn't look like CTS has any coverage for this yet so it has only
been smoke tested, but it seems to be working correctly, as expected.
