JSX v4 shared props

[mununki]

This PR adds a new feature for JSX v4 which is using shared props type as an argument of @react.component
#695

Example

type sharedProps<'a> = {x: 'a, y: string} // original module V4C2 = { @react.component(:sharedProps<'a>) // <- here let make = (~x, ~y) => React.string(x ++ y) } // converted to module V4C2 = { type props<'a> = sharedProps<'a> @react.component(: sharedProps<'a>) let make = ({x, y, _}: props<'a>) => React.string(x ++ y) let make = { let \"SharedProps$V4C2" = (props: props<_>) => make(props) \"SharedProps$V4C2" } }

Great work! Thanks a lot! 🎉

All the tests have sharedProps<'a> with a single type parameter. Maybe also add a test with no type parameter and a test with more than one.

Sorry, every time I forgot the changelog. I’ll add it on another PR.
