Read constants header instead of global platformConstants
With this patch we switch from reading the globally installed
platformConstants file to reading the DerivedConstants.h header file
that is bundled in the RTS unit. When we build the RTS unit itself, we
get it from its includes directories.
The new parser is more efficient and strict than the Read instance for
PlatformConstants and we get about 2.2MB less allocations in every
cases. However it only really shows in tests that don't allocate much,
hence the following metric decreases.
