perf ui hists: In report UI ensure thread is set with reference counting

Browse source

Populates the map_symbol thread in the UI code to fix the e_machine
lookup for cross-platform disassembly when using the annotate action.
At the same time, refactor the UI options and actions generation to
comply with the perf subsystem's strict reference counting abstraction
requirements for 'struct map_symbol' and 'struct thread'. Introduce
explicit reference acquiring via map_symbol__copy() and thread__get() for
menu items, safely clean them up between menu iterations using a new
free_popup_actions() helper, and utilize insulated temporary action
variables for direct hotkey handler execution.
