tracing/fastboot: move boot tracer structs and funcs into their own header.
Impact: Cleanups on the boot tracer and ftrace This patch bring some cleanups about the boot tracer headers. The functions and structures of this tracer have nothing related to ftrace and should have so their own header file.
