perfmon: make less arch dependent
In preparation for enabling perfmon on Arm platforms, move some Intel /arch specific logic into the /intel directory and update the CMake to split the common code from arch specific files. Since the dispatch_wrapper code is very different on Arm/Intel, each arch can provide their own implementation + conduct any additional arch specific config e.g. on Intel, all indexes from the mmap pages are cached. The new method intel_config_dispatch_wrapper conducts this config and returns a pointer to the dispatch wrapper to use. Similarly, is_bundle_supported() looks very different on Arm/Intel, so each implementation is to provide their own arch specific checks. Two new callbacks/function ptrs are added in PERFMON_REGISTER_SOURCE to support this - .bundle_support and .config_dispatch_wrapper. Type: refactor Signed-off-by: Zachary Leaf <zachary.leaf@arm.com> Change-Id: Idd121ddcfd1cc80a57c949cecd64eb2db0ac8be3
