Move src/app configuration to generated header (#7789)

We generate headers containing build time configuration choices for good
reason: some builds use multiple build systems and writing out a header
is how we ensure consistent choices are made between them (thus avoiding
ODR violations that can cause catastrophic breakage).

Move the command line #defines for src/app to a new generated header.
This makes it safe to enable schema checking in hybrid builds if this is
desired.
