[PS4] Always enable the .debug_aranges section when using LTO 

This flag enables the .debug_aranges section by passing a flag to LLD
and our internal linker. This also adds a new routine that will generate
the correct flag for our internal linker or set of flags for LLD when
given a list of LLVM options. That ensures multiple LLVM codegen options
can be passed to either linker consistently.
