selfboot: Add support for selfload in romstage
Since bootmem is not available in romstage, calls to bootmem APIs need to be compile-time eliminated in order to avoid linker error: undefined reference to `bootmem_region_targets_type BUG=None BRANCH=None TEST=./util/abuild/abuild -p none -t GOOGLE_HEROBRINE -x -a -B cherry-picked on top of CB:49392 and verified successful compilation.
