Compile each project's PCH to a separate file to reduce developer friction. (#3505) 

Having to remove the precompiled header when switching from firmware to simulator to unit_tests and
back again is annoying.  Use a directory to store the precompiled header output.  Turn off
precompiled header warnings as GCC still complains even if it finds a valid one eventually.
