perf parse: Refactor 'struct perf_evsel_config_term'

The struct perf_evsel_config_term::val is a union which contains fields
'callgraph', 'drv_cfg' and 'branch' as string pointers.  This leads to
the complex code logic for handling every type's string separately, and
it's hard to release string as a general way.

This patch refactors the structure to add a common field 'str' in the
'val' union as string pointer and remove the other three fields
'callgraph', 'drv_cfg' and 'branch'.  Without passing field name, the
patch simplifies the string handling with macro ADD_CONFIG_TERM_STR()
for string pointer assignment.

This patch fixes multiple warnings of line over 80 characters detected
by checkpatch tool.
