Revert "[Comgr] Add -relink-builtin-bitcode-postop to device library …

…linking"

This reverts commit 005d151.

This commit can be reverted for 6.1 release branch:
  - Only hipRTC uses the COMPILE_SOURCE_WITH_DEVICE_LIBRARIES_TO_BC
  - For hip contexts we don't run AMDGPUSimplifyLibCalls, so relinking
       isn't needed

 - Added -x assembler option to assembly compilation. Before, if an assembly file
 did not end with a .s file extension, it was not handled properly by the Comgr
 ASSEMBLE\_SOURCE\_TO\_RELOCATABLE action.
-- Added new -relink-builtin-bitcode-postop LLVM option to device library. This

-OpenCL applications that leveraged AMDGPUSimplifyLibCalls optimizations would
