[Runtimes] Merge 'compile_commands.json' files from runtimes build (#116303)
Summary:
When building a project in a runtime mode, the compilation database is a
separate CMake invocation. So its `compile_commands.json` file will be
placed elsewhere in the `runtimes/runtime-bins` directory. This is
somewhat annoying for ongoing development when a runtimes build is
necessary. This patch adds some CMake magic to merge the two files.
