x86: turn 64 bit x86 HANDLE_STACK into print_context_stack like 32 bit has

This patch turns the x86 64 bit HANDLE_STACK macro in the backtrace code
into a function, just like 32 bit has. This is needed pre work in order to
get exact backtraces for CONFIG_FRAME_POINTER to work.

The function and it's arguments are not the same as 32 bit; due to the
exception/interrupt stack way of x86-64 there are a few differences.

This patch should not have any behavior changes, only code movement.

Due to the fragility and importance of the backtrace code, this needs to be
well reviewed and well tested before merging into mainlne.
