perf annotate: Track address registers via TSR_KIND_POINTER

Introduce TSR_KIND_POINTER to improve the data type profiler's ability
to track pointer-based memory accesses and address register variables.

TSR_KIND_POINTER represents that the location holds a pointer type to
the type in the type state. The semantics match the `breg` registers
that describe a memory location.

This change implements handling for this new kind in mov instructions
and in the check_matching_type() function. When a TSR_KIND_POINTER is
moved to the stack, the stack state size is set to the architecture's
pointer size.
