Enable some rendering tests (#5623)

* render-test: Add copy-source usage for render targets

I found that Slang-RHI/WGPU was not able to copy from render targets to staging buffers.

This helps to address issue #4943.

* Add entries to render API util infos

Entries for glsl-cross and glsl-rewrite are added.

Without glsl-cross, slang-test fails to select a back-end, and winds up crashing when
tests/render/cross-compile-entry-point.slang is enabled

tests/render/cross-compile0.hlsl fails similarly without glsl-rewrite.

* Enable some rendering tests

* Add expected test outputs
