Subject: [PATCH] [rocprofiler-sdk] allow using system elfio dependency

This adds a new option, ROCPROFILER_BUILD_ELFIO, which can be set to OFF to
make rocprofiler use a system dependency for ELFIO instead of trying to build
it manually. To mimick old behavior, ROCPROFILER_BUILD_ELFIO is set to ON by
default.
