arch: introduce option to force internal architectural state init

We introduce an option that instructs Zephyr to perform
the initialization of internal architectural state (e.g.
ARCH-level HW registers and system control blocks) during
early boot to the reset values. The option is available
to the application developer but shall depend on whether
the architecture supports the functionality.
