Split building coreboot toolchains to a separate file

Specify dependencies specifically for building coreboot toolchains in
the file, so they are not conflated with the dependencies required for
building firmware-open.

Remove building the toolchain when building firmware, so that the new
script is the single source for building coreboot toolchains.
