video_core: Various small improvements and bug fixes (#2525)

* ir_passes: Add barrier at end of block too

* vk_platform: Always assign names to resources

* texture_cache: Better overlap handling

* liverpool: Avoid resuming ce_task when its finished

* spirv_quad_rect: Skip default attributes

Fixes some crashes

* memory: Improve buffer size clamping

* liverpool: Relax binary header validity check

* liverpool: Stub SetPredication with a warning

* Better than outright crash

* emit_spirv: Implement round to zero mode

* liverpool: queue::pop takes the front element

* image_info: Remove obsolete assert

The old code assumed the mip only had 1 layer thus a right overlap could not return mip 0. But with the new path we handle images that are both mip-mapped and multi-layer, thus this can happen

* tile_manager: Fix size calculation

* spirv_quad_rect: Skip default attributes
