[Slider] Added an option to allow a subset of tick marks in discrete mode

[gabrielemariotti]

With this option you can use a subset of the tick marks in respect of stepSize attribute.

Example:

  <com.google.android.material.slider.Slider
    android:valueFrom="0"
    android:valueTo="1000"
    android:stepSize="50"
    app:tickValues="@array/subset_tick_values" />

with:

  <array name="subset_tick_values">
    <item>0.0</item>
    <item>100</item>
    <item>250</item>
    <item>500</item>
    <item>750</item>
    <item>1000</item>
  </array>

The tickValues must contain values:

• >= valueFrom
• <= valueTo
• = valueFrom + a multiple of stepSize
