Optimize My Data Screen Performance

[sternetj]

Changes

• Fixes an issue with the LineChart TrendLine computing an infinite slope
• Adds a loader to the LineChart
• Adds enabled props to all charts to control when searching occurs
• Hides DataSelector for LineChart when not enabled. When view a year's worth of data, the component creates a lot of children which causes the render to be slow. This hides the DataSelector for non-enabled charts. Ultimately this needs to be reworked but it's okay for now
• Fixes a bug with sleep chart multiday selection where trying to select a chart with no data caused an error
• Adds the ability provide a Header to the SurfaceView. This is useful for providing a fixed header
• Fixes the styles of the DatePicker to fit in a flex layout better and to have a shadow to since it should be slightly elevated
• Adds scroll observing behavior to only fetch data for charts that are visible to the user
• Extracts the range selector control so it is more responsive to touches and uses a debounced change method to prevent the my data charts from refetching too soon
