refactor: remove obsolete OptiX PTX scratch files and stale sysrap test runners (#343)

This PR removes outdated OptiX/PTX scratch code and related stale test artifacts.

### CSGOptiX cleanup

- remove the obsolete `CSGOptiX/Check.cu` debug/probe source
- simplify `CSGOptiX/CMakeLists.txt` now that `CSGOptiX7.cu` is the only remaining OptiX PTX source
- keep the PTX object/install wiring aligned with the single-source setup

### sysrap test cleanup

- remove stale `SOPTIX_Module_test.{cc,sh}` and `SOPTIX_Pipeline_test.{cc,sh}` files
- remove the obsolete `sysrap/tests/go.sh` runner and its `tests.txt` manifest
- clean up leftover references in `sysrap/SOPTIX.rst` and `sysrap/SGLFW_Evt.h`

## Why

`Check.cu` was an old standalone compiler/debug check and is no longer part of the active OptiX path.

The removed `sysrap` test files were stale, not wired into the current CMake test flow, and still referenced outdated PTX naming/path conventions. Existing OptiX integration paths already exercise module/pipeline creation more realistically through current render/simulate flows.
