SystemUI: Introduce user interface for Alert Sliders

Ported from OxygenOS and reworked for our alert slider
implementation. We target AudioManager instead of Zen,
icons are also the same as aosp and the dialog uses the
material theme as well as support for our themes.

To use, the alert slider config must be enabled. By default,
the dialog shows on the left side. To move it to the right
side, set the location config to 1.

also squashed with the following changes:

    [aospa][quartz] SystemUI: Improve alert slider dialog

    - Convert px to dip
    - Modify the dialog to match toast
    - Fix positioning for OP7 Pro slider
    - Remove unused dimens and drawables

    Edit: set position values to 0 for neutrality. They should
    be adapted by overriding in each device tree.

    * In intent extra EXTRA_SLIDER_POSITION_VALUE is not received and slider is changed,
      SystemUI will crash "No resource found". This patch should prevent such ice-cold havoc.
