HaikuDepot: Drop Caches on Version Change

To avoid having to upgrade cache-data formats,
drop the caches when the application starts with
a different version from last time the
application launches.

HaikuDepot: Refresh Repo Cache

When HD first loads in a new install, it will experience
a near-empty set of repositories. This is because only
build-time repo caches are present. This change will
cause HD to pull data from remotes on first load, in the
case that the cache is somehow missing and on a user-
initiated update.

Resolves #14840

HaikuDepot: Check Working Files Writable

At start time, it is possible that the local disk
system is not able to be written to where the
application is trying to store working files. This
change introduces a check at startup that ensures
working files can be written to and warns the user
if this is not the case.

HaikuDepot: Process and Data-loading Improvements

This change is a reshuffle of the backend processing involved in the
aquisition of data from servers including the pull-down and load of
HPKR data as well as the pull-down and load of data from the
HaikuDepotServer (HDS) system. The driver for this change is to
implement an initial implementation of a progress bar for the
loading of data as the application starts.

The following are notable changes;

* Removed some previously attempted 'functional style' logic in the
model which didn't fit well with C++
* Use of the base-url in the logical mapping from HDS and HD data is no
longer required and has been removed
* Some logging has been improved making it clearer which part of HD
is producing the logging which in turn helps with debugging issues
* List class has been modified to more cleanly support sorted lists
and binary searches; tests have also be updated accordingly
* Reorganise and tidy-up of the data-loading processes' structures
* The local repository update (HPKR) and data-load occur in background
processes now in the same system as the HDS data-load - this has been
crudely shifted from the MainWindow to new Processes and incorporated
into the background processing system
* The 'state-machine' background process runner is now replaced with a
'coordinator' style approach that can more easily handle the new
processes related to HPKR loading.
* Progress for loading processes is shown in the main window in the
WorkStatusView - this is flickering a bit, but basically works
* Added some documentation regarding how Processes work in the system
* The "Refresh Repositories" menu item now also updates data from HDS
* The "Refresh Repositories" menu item is disabled when the background
processes are running that update the repository data

Some further refinement would be good, but this change is large enough
for one round of improvements. There is an issue that the status bar
is used for screenshot display as well as this data-loading, but that
was the case before so it is something that can be dealt with later if
it is a problem.

HaikuDepot: change window frame setting.

* Moved entirely into MainWindow.
* Moved duplicated code into separate methods.
* Resize the main window on larger screens by default, as we can make
use of the extra space.
* Use BWindow::MoveOnScreen() instead of make_sure_frame_is_on_screen()
as the former has more info. And is even smarter now as it can
optionally resize windows to fit on screen.
* Center window on screen by default (ie. when there are no settings).

HaikuDepot: Check if package_daemon runs and offer to start it

Fixes ticket #9967.

HaikuDepot: WIP to open .hpkg files.

* When opening .hpkg files, shows just the PackageInfoView in a smaller
window.
* PackageInfo constructor with BPackageInfo argument
* Default pkg icon has a single instance only. Before, there would be another
instance for each repository refresh.

TODO:
* Install button on single package view is non functional
* Probably needs to do someting different when opening .hpkg from an
installed packages folder (show the regular list and focus that package?).
* The filter view and list view are still constructed for the single package
mode.
* ...
