[SYCL][ESIMD][EMU] Preventing 'cmrt_dump.txt' generation from CM

[dongkyunahn-intel]

• CM library used by ESIMD_EMULATOR support generates 'cmrt_dump.txt'
  file for debugging

• This patch prevents file generation

• cmrt_dump.txt generated  #5379

[dongkyunahn-intel]

This patch removes following line, and CM library package is generated without debug support, which generates cmrt_dump.txt.

@pvchupin, could you take a look, please?

It requires detailed explanation in PR description what's going on here and why this change is needed.
It looks like we may have design problem over the full stack?

@pvchupin ,

Until CM library package used by ESIMD_EMULATOR is provided as pre-built one, it needs to be built during intel/llvm toolchain build by downloading & building source files from https://github.com/intel/cm-cpu-emulation. The CMakeLists.txt file modified in this ticket takes care of CM library generation.

CM library package built during esimd_emulator PI module build is generated as debug build. This build configuration happens to leave empty cmrt_dump.txt file after kernel execution (#5379). As it could take a while for open-source CM library to be updated to prevent debug file generation, I applied online-patching for CM library to be built as Release build. This PR is for the online-patching.

I'm to release CM EMU with this issue fixed shortly, so this change will not be needed.

I'll close this PR when open-source CM EMU is updated.

@dongkyunahn-intel , @lsatanov thank you. That would be the best approach imo.
