Fix major issues with `LongPress` gesture on web

[j-piasecki]

Description

This PR solves a few issues with LongPress gesture on web:

• adds a duration property to events send by the gesture
• fixes a bug where onBegin and onStart would not be called because of wrong oldState value in the events sent by the web implementation
• fixes a bug where no events would be called if the gesture failed, now it correctly calls onBegin and onFinalize if the press time is too short

(Mostly) fixes https://github.com/software-mansion/react-native-gesture-handler/issues/2063

Test plan

Tested on the Example app.
