Attempting to set the window title of a BrowserDock that is closed, then
opening the BrowserDock, would show that BrowserDock with an incorrect
title. We can handle this by overriding the showEvent of BrowserDock and
manually setting the window title after the showEvent is called,
hopefully ensuring that we are only setting the window title on a window
that exists.
Instead of relying on the dock's having their window title already set
for the menu items to be updated, let's just manually update the menu
item text ourselves when updating the item.
This is a workaround for a change in Qt behavior between 6.5.1 and
6.5.2[1] which affected the outcome of attempting to set the window
title of a window that is not currently open. In Qt 6.4.3 and 6.5.1, the
window title would be set. In Qt 6.5.2, the window title will become
NULL/empty.
Instead of relying on Qt to have valid titles for custom browser dock
windows that we manage, let's track the names ourselves.

Works around a bug in Qt where setWindowTitle called on a native window
that hasn't been initialised yet causes the title data to be lost,
resulting in the window's title never being set.
Use the QAction provided by QDockWidget with new Qt connection rather
than creating a new one for each dock.
Separate extra browser docks from extra docks, the latter is meant for
plugin/integration docks.
The removeIconSmall is now also a trash icon, so we don't need a
separate (now duplicate) themeID for it anymore.
The icon itself of course needs to stay as it's still needed.
The extra browser panels would always create on startup due to the
visibility change. This fixes that by ensuring that this call blocks
signals, and ensures that the call only happens on first creation by the
user and not when the user is loading on startup.
In the view -> Docks menu, when a user first creates a custom browser
dock, the menu item associated with them used to hide/show them will be
unchecked in the menu by mistake. This ensures they're checked when
first created.
Allows the ability for users to add custom browser widget docks that
they can use for their third party services if they feel the need,
mostly as a convenience tool so they don't have to open extra browsers
alongside the program.
