Remove hip-hcc codes: Part four

Remove __HCC__, __HCC_ONLY__, __HCC_CPP__, __HCC_C__,
__HCC_OR_HIP_CLANG__, __HIP_ROCclr__ and their guarded codes.

Remove Hcc codes from directed_tests and samples.

Remove __HIP_PLATFORM_HCC__ and __HIP_PLATFORM_NVCC__ from
some files where they are not necessary.

Add deprecation notice.
