TS: Add all valid props to Content interface

[emily-curry]

Based on the react-native-keyboard-aware-scroll-view docs (which the Content component wraps), this component should be able to accept all ScrollView props, as well some additional props to control the keyboard-aware-scroll-view (which have been directly copied from that project's d.ts, as it does not export it's props). All redundant props have been removed from the interface.

@Shurelia Can you explain me, why is contentContainerStyle and few other props excluded in your PR?

[emily-curry]

Hey @SupriyaKalghatgi,
Those props are excluded because I changed Content to extend ReactNative.ScrollViewProperties. contentContainerStyle and those other excluded props are part of ScrollViewProperties.
