This pull request is the second part of an ongoing effort to extends PGO instrumentation to GPU device code and depends on #76587. This PR makes the following changes: - Introduces `__llvm_write_custom_profile` to PGO compiler-rt library. This is an external function that can be used to write profiles with custom data to target-specific files. - Adds `__llvm_write_custom_profile` as weak symbol to libomptarget so that it can write the collected data to a profraw file. - Adds `PGODump` debug flag and only displays dump when the aforementioned flag is set
