perf annotate: Move the data structures related to register type to header file

Data type profiling uses instruction tracking by checking each
instruction and updating the register type state in some data
structures.

This is useful to find the data type in cases when the register state
gets transferred from one reg to another.

Example, in x86, "mov" instruction and in powerpc, "mr" instruction.

Currently these structures are defined in annotate-data.c and
instruction tracking is implemented only for x86.

Move these data structures to "annotate-data.h" header file so that
other arch implementations can use it in arch specific files as well.
