CModule is now a feature which can be enabled or disabled. It is enabled by default.
Symbol prefixing is now a feature which can be disabled. Largely due to this causing issues when embedded bitcode (symbols are non-renamed inside the bitcode and therefore the linker gets confused).
Embed bitcode - support for including bitcode in the builds.
This PR adds 3 new features/options to the build.
Depends on an update to releng: https://github.com/frida/releng/pull/4
