Using GtkToggleButton in this case is not only overkill for our
intended use case, it is also a hinderance, as the states and focus
of the widget are handled by the widget itself, which can lead to
unpredictable and undesired behavior.
Using AdwBin solves this problem by allowing us to set the styles
and states from the parent, provided that the CSS name is changed
to "button". Switching to AdwBin also allows us to not override the
`focus()`, `grab_focus()`, and `get_platform_state()` virtual methods.

This is a prerequisite for removing the strong dependence on the
child GtkToggleButton widget, removing the platform state override,
and adding binding actions in later commits.
Inheriting AdwBin was attempted but it didn't work, as AdwBin
presumably messes with focusability and activation, making
it insufficient for this use case.
`hexpand=true` needs to be explicitly set.

We no longer use this property. Removing it will then allow us to
directly set the label without having to use GtkStack, but this
will be done in a later commit.
This also sets all transitions to "none".

When clicking the previous/next buttons, the view might not be aligned
to the start of the month, which can cause confusion.
Clamping the date to the first of the month removes this confusion by
being consistent. This also matches the behavior of the previous/next
buttons in the main toolbar.

Instead of applying the "dimmed" CSS class - which comes from Adwaita
and applies an overall opacity change - add a new custom "past" CSS
class and change the opacity of specific elements.
This avoids opacity in the group, which in turn allows GTK to avoid
rendering these event widgets in offscreens, which should be faster.

This is a utility widget akin to GtkGizmo[1] and AdwGizmo[2].
It is designed for use in complex widgets which require additional
features such as snapshotting, measuring/allocating, and
focusing capabilities.
We want to implement an entry row widget that allows multi-line content.
The first implementation had two widgets: GcalNotesRow for the widget
itself, and GcalNotesTitle to contain and animate the title by overriding
the measure() and size_allocate() class methods. The GcalNotesTitle
widget ended up becoming a basic widget that could easily be handled
by GcalGizmo. The new implementation simply uses GcalGizmo.[3]
Another potential user of GcalGizmo is GcalDateChooser, where the
date grid contains complicated logic for handling focus to a child widget.
Since GcalGizmo is designed to give full reign over focusability, we can
also use it to simplify focus. The layout manager can quickly be swapped to
GtkBinLayout since we don't want to handle custom measure/allocation logic.[4]
