Xtensa port: Added Xtensa specific code (C + S) files. Change-Id: I0dff0c33d8577cc70d4d5ee8f298db38c508ee73 Signed-off-by: Mazen NEIFER <mazen@nestwave.com>

cleanup: include/: move tracing.h to debug/tracing.h move tracing.h to debug/tracing.h and create a shim for backward-compatibility. No functional changes to the headers. A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES. Related to #16539 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

kernel: add arch interface for idle functions k_cpu_idle() and k_cpu_atomic_idle() were being directly implemented by arch code. Rename these implementations to z_arch_cpu_idle() and z_arch_cpu_atomic_idle(), and call them from new inline function definitions in kernel.h. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

debug: tracing: Remove unneeded abstraction Various C and Assembly modules make function calls to z_sys_trace_*. These merely call corresponding functions sys_trace_*. This commit is to simplify these by making direct function calls to the sys_trace_* functions from these modules. Subsequently, the z_sys_trace_* functions are removed.

xtensa: use inline assembly instead of XT_* macros XT_* macros are defined in xtensa HAL headers as xcc intrinsics. gcc does not have any of these intrinsics. Replace XT_* macros with inline assembly or provide gcc-compatible definitions. Change-Id: If823ea8a7898a11a3a8363b17efdba27dee4c6a4 Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
