Add a Dockable HTML Panel API for Plugins (#15736)

Browse Source 
orca.host.ui.create_dock_panel(html, title, width, height, on_message,
on_close, dock) hosts plugin HTML in a pane of the Plater's dock manager,
next to the sidebar, and returns a UiDockPanel handle
(post/show/hide/close/is_open). The arguments follow create_window(). The
panel uses the window.orca bridge of plugin windows, restores its position
and size from the saved window layout, hides with the Plater off the Prepare
and Preview tabs when floating, and is closed with its plugin; plugin panes
are removed in MainFrame::shutdown().

The web view hosting moves out of PluginPage into a shared WebPanel base:
bootstrap page and swap to the plugin HTML, theme, element-default and
bridge scripts, window.orca message parsing, delivery to the page, and live
re-theming, also re-applied on every load after the swap. Pages tabs and
docked panels both derive from it. Pages tabs now re-theme in place on a
theme change instead of being reloaded, and a window.orca call a host does
not support is logged.

What the hosts share no longer lives in one of them: the bootstrap page, the
base URL and the plugin-window bridge move to Widgets/WebHosting, used by
WebDialog and WebPanel alike. The Plater restores plugin panes with a new
saved-layout parser, GUI/AuiPaneLayout, kept in its own small header so
slic3rutils can test it without pulling in the Plater.

The web hosting classes carry no plugin name, so other hosts can reuse them:
PluginWebDialog becomes WebDialog (its bootstrap page moves to
resources/web/dialog/WebDialog), and destroy_for_plugin(),
load_plugin_content() and plugin_defaults_user_script() become
destroy_silently(), load_page_html() and element_defaults_user_script().

Includes a sample plugin (sandboxes/orca_dock_panel_plugin_any.py) and
binding and layout-helper tests in slic3rutils.
