utils: add postinstall.py

Replace ConfigureOs script by native calls to:

- update BCD via hivex using bcd.py and winreg.py infrastructure.
- restore efi bootloader restore_windows_efi_bootloader().

Call legacy scripts for remaining postinstall procedures to
replace them incrementally.

Define variable CONFIGUREOS_LEGACY_ENABLED as False by default.
Run legacy configureOs when CONFIGUREOS_LEGACY_ENABLED = True.
This serves as a auxiliar method to keep the restoration functional
in case of problems with the new configure_os logic.
