[TreeView] Add indeterminateCheckboxAction prop

[flaviendelangle]

Follow up on #14899 to bring to bring #14247 to the Tree View

Here is the prop on the grid:

  /**
   * If `select`, a group header checkbox in indeterminate state (like "Select All" checkbox)
   * will select all the rows under it.
   * If `deselect`, it will deselect all the rows under it.
   * Works only if `checkboxSelection` is enabled.
   * @default "deselect"
   */
indeterminateCheckboxAction?: 'select' | 'deselect'

We should have the exact same DX on the Tree View and the doc example should be as similar as possible

Context from the Data Grid, we should make sure we follow the same path.
