cpu/x86/Kconfig: Mark 64bit support as stable
With SMM holding page tables itself, we can consider SMM support stable and safe enough for general use. Also update the respective documentation.

Enable experimental support to build and run coreboot in 64-bit mode.
When selecting this option for a new platform, it is highly advisable
to provide a config file for Jenkins to build-test the 64-bit option.

When set, most of coreboot runs in long (64-bit) mode instead of the
usual protected flat (32-bit) mode. 64-bit CPUs and OSes can be used
- irrespective of whether coreboot runs in 32-bit or 64-bit mode. This
- is an experimental option: do not enable unless one wants to test it
- and has the means to recover a system when coreboot fails to boot.
