targets: move early_boot.c to boot.cc
Alters the existing targets to use a boot.cc file instead of the
existing early_boot.c.
The name was updated to reflect the fact that it now contains a
pw_boot_PostMain() hook which is after early boot.
C++ was selected over C to give more language flexibility.
