Increase maximum number of tracked pointers (#3915)

## Description

Gesture Handler has a limit of maximum tracked pointers that currently
is set to 12. This PR increases this value to 17 (found empirically to
be the limit on `iOS`).

## Test plan

1. Unfortunately I don't have 17 fingers but trust me (and @jp) bro
2. Build example app on both platforms
