[MaterialToolbar] SearchView text/hint not using colorOnPrimary

Nobody has claimed this yet.

**Description:**
When having the following layout defining the toolbar:
```

```
The colors of the Toolbar (title, subtitle, icons, ...) are set correctly to `?attr/colorOnPrimary`. However, the text and hint of the SearchView are not.

**Expected behavior:**
I would expect the colors of the SearchView to be the same as the tile/subtitle of the Toolbar.

**Source code:**
The definition of [ThemeOverlay.MaterialComponents.Toolbar.Primary](https://github.com/material-components/material-components-android/blob/712a2ce92040b6fc90530ad853633ecd7f258dfc/lib/java/com/google/android/material/appbar/res/values/styles.xml#L77-L80) is missing the color settings for the SearchView:
```

<item name="colorControlNormal">?attr/colorOnPrimary</item>
<item name="actionMenuTextColor">?attr/colorOnPrimary</item>

```
When overriding the default ThemeOverlay with the following, it works fine:
```

<item name="android:editTextColor">?attr/colorOnPrimary</item>
<item name="android:textColorHint">?attr/colorOnPrimary</item>

```

Start with lib/java/com/google/android/material/appbar/res/values/styles.xml, specifically ThemeOverlay.MaterialComponents.Toolbar.Primary and its existing color settings. Verify the SearchView text and hint colors under this overlay, then confirm that they match the toolbar title and subtitle colors.
