arch/x86: Clarify help text for 64-bit support

The word "experimental" has been removed from the help text for
HAVE_X86_64_SUPPORT Kconfig. This is because the x86_64 architecture
has now been officially tested and enabled for several x86 SoC
platforms.

This work will provide us with the foundation we need to begin working
with Intel's next-generation SoC platform (which requires to support
64-bit mode of booting by default).

Therefore, we can now remove the word "experimental" from the
"HAVE_X86_64_SUPPORT" Kconfig help text.

TEST=Able to build and boot google/rex64 in 64-bit mode to ChromeOS.
