Show a warning dialog about charges when user starts a video call
The user starts a video call a warning dialog shall be presented. If the user presses "OK" with the "Do not show again" box selected, the dialog shall not be presented anymore. Test: manual - Verified that a warning dialog about charges is shown when a video call is started if KEY_SHOW_VIDEO_CALL_CHARGES_ALERT_DIALOG_BOOL is true. This is an upstream change from: https://android-review.googlesource.com/c/platform/packages/apps/Dialer/+/518977/8 Bug: 67832837 Test: partner manual test PiperOrigin-RevId: 188103414 Change-Id: I62628a32557297acaef096db90d2ddf049ef5017
