Also update the rest of the symbol-chooser usage to current
specs, including examining the timestamp to see if the list
needs loading at all.
Partial fix to: lp:1760936

While we already cache the loaded footprint files, parsing said files
into the list is also time-intensive. Since the FOOTPRINT_LIST is
already hash-stamped against the current timestamps of the files that
make up the list, sharing a single copy of the list is quite
straight-forward.
DIALOG_COMPONENT_CHOOSE displays footprint preview when pcbnew kiface
is available, but it crashed when it was not in the same directory
as the executable. Now it displays an error message that allows the
user to quickly identify the problem.

Fix incorrect frame deletion, only noticeable when eeschema is run in stand alone mode.
After selecting a footprint using the footprint viewer, the application cannot be closed.
Reason:
the footprint viewer ctor creates an instance (not shown) of a FRAME_PCB.
Unfortunately, this pcb frame was not deleted by Eeschema, in stand alone mode,
preventing the application to be closed because a frame was still active after closing the schematic editor frame.
Now the footprint viewer ctor delete this instance after use, if it was not previously existing.

- DIALOG_CHOOSE_COMPONENT has footprint select widget
- FOOTPRINT_SELECT_WIDGET
- FOOTPRINT_CHOICE widget (customized wxComboCtrl)
- FOOTPRINT_FILTER class
- FOOTPRINT_INFO rework:
- FOOTPRINT_ASYNC_LOADER to load without freezing UI
- Rewrite loader threads as queue-driven thread pool
- Make FOOTPRINT_INFO available via kiway
- FP_LIB_TABLE::PrefetchLib
- Access to global fp-lib-table via kiway
- SYNC_QUEUE threadsafe queue template
- Remove KICAD_FOOTPRINT_SELECTOR build option
