perf annotate: Introduce global annotation_options
[ Upstream commit 9d03194a36345796d4f0f8d6b72eb770a45d614e ]
The annotation options are to control the behavior of objdump and the
output. It's basically used by 'perf annotate' but 'perf report' and
'perf top' can call it on TUI dynamically.
But it doesn't need to have a copy of annotation options in many places.
As most of the work is done in the util/annotate.c file, add a global
variable and set/use it instead of having their own copies.
