build system: Structure and serialize INTERMEDIATE

Target added to INTERMEDIATE all operate on coreboot.pre, each modifying
the file in some way. When running them in parallel, coreboot.pre can be
read from and written to in parallel which can corrupt the result.

Add a function to create those rules that also adds existing
INTERMEDIATE targets to enforce an order (as established by evaluation
order of Makefile.inc files).

While at it, also add the addition to the PHONY target so we don't
forget it.

BUG=chromium:1154313, b:174585424
TEST=Built a configuration with SeaBIOS + SeaBIOS config files (ps2
timeout and sercon) and saw that they were executed.
