Add prop to improve performance of MapView (47)

[YoussefHenna]

• When the tracksViewChanges prop on markers is enabled, every marker on the screen keeps track of changes in the parent view. When there are many markers, this can create a sluggish and laggy map when trying to drag/pan (most noticeable on android).
  • This prop is enabled by default - https://github.com/react-native-maps/react-native-maps/blob/master/docs/marker.md#props
• This PR temporarily disables the prop when dragging then enables it after dragging stops
• Disabling entirely creates another issue where markers and clusters are never updated, so this is best solution to prevent laggy panning while still allowing markers and clusters to be able to update.

P-4143 Performance Issue with Map Component on Android.

This issue seems to due to custom marker images and a lot of markers being rendered on the map.

Initial Investigation:

• Tried reducing the size of marker images, but it's still lagging on Android.

• Verified by removing the custom marker images,  works well

This is impacting the final delivery of an expert app, so I am keeping it as a high priority.
