[TimePickerDialog] Dynamic Theme at runtime

Similar to https://github.com/material-components/material-components-android/issues/2586 just for TimePickerDialog.

We're targeting B2B and they want to brand the app at runtime with corporate colors.

Meaning every single color can be changed at runtime. In order to achieve this I don't use any styles or themes in order to tint my views. In order to spot any views that are not using the runtime tint, I have the following theme:

  <style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <item name="colorOnPrimary">#FF62FF00</item>
    <item name="colorOnSecondary">#FF62FF00</item>
    <item name="colorPrimary">#FF62FF00</item>
    <item name="colorPrimaryDark">#FF62FF00</item>
    <item name="colorSecondary">#FF62FF00</item>
    <item name="android:navigationBarColor">#FF62FF00</item>
    <item name="android:textColor">#FF62FF00</item>
  </style>

With this theme I can spot views that are not behaving easily as things are shown in an aggressive green.

Right now, every component from Material can easily be tinted by subclassing and setting various properties:

• rippleColor
• iconTint
• backgroundTintList

We are already successfully using Fab, BottomNavigation, Toolbars, Buttons etc.

TimePickerDialog can't be themed at runtime. Ideally, I'd like to tint the following 'Views':

• all text colors
• clock color
• selected/unselected state (am/pm)

Start by reading the linked issue 2586 and inspecting the existing TimePickerDialog implementation. Identify how its text, clock, and AM/PM selected-state colors are sourced at runtime. Done means those areas can be changed through runtime tinting without relying on static styles or themes.
