arch: arm64: Introduce ARM64 (AArch64) architecture Introduce the basic ARM64 architecture support. A new CONFIG_ARM64 symbol is introduced for the new architecture and new cmake / Kconfig files are added to switch between ARM and ARM64. Signed-off-by: Carlo Caione <ccaione@baylibre.com>

arm64: implement exception depth count Add the exception depth count to tpidrro_el0 and make it available through the arch_exception_depth() accessor. The IN_EL0 flag is now updated unconditionally even if userspace is not configured. Doing otherwise made the code rather hairy and I doubt the overhead is measurable.

arm64: optimize offsets in z_arm64_context_switch We can use build-time offsets from a struct k_thread pointer directly to struct _callee_saved members. No need to compute that at run time. Signed-off-by: Nicolas Pitre <npitre@baylibre.com>
