Complete `Pressable` refactor.

[latekvo]

Description

This PR introduces a complete Pressable refactor. New Pressable version defines sequences of events required to activate different Pressable callbacks. This approach allows for fewer edge-case controls, and features a much cleaner code base & a clear execution flow. The new implementation also makes detection and handling of new, unexpected cases much simpler.

Fixes

• Fixes #3476
• [iOS] Short taps were ignored when within a list
• Ordering of onPress* was chaotic. Aligned it to the documentation.

Completion checklist

• onPress*
  • [x] callbacks
  • [x] support hitSlop
  • [x] support unstable_pressDelay
• onHover* callbacks
  • [x] callback
  • [x] support delayHoverIn, delayHoverOut
• onLongPress support
  • [x] callback
  • [x] support delayLongPress
• [x] ref passthrough support
• Android support
  • [x] on fabric
  • [x] on paper
• iOS support
  • Note: There's a 200ms delay before onPressIn when long-pressing in a scroll list. This is an intentional "feature" within iOS, but RN Pressable manages to avoid it.
  • [x] on fabric
  • [x] on paper
• [x] Web support
• MacOS support
  • [ ] on fabric
  • [x] on paper
• [x] style & children support

Test plan

Use all the existing Pressable examples to test the behaviour of the newly added pressable.

Make sure to test on the following platforms:

• Android fabric
• Android paper
• iOS fabric
• iOS paper
• MacOS fabric
• MacOS paper
• Web

Make sure to also test the following scenarios:

• Pressable is not nested, and is not within a ScrollView
• Pressable is nested within another Pressable, without a ScrollView
• Pressable is nested within another Pressable, which is nested within a RNGH ScrollView
• Pressable is nested within another Pressable, which is nested within a RN ScrollView
• Pressable is nested within another Pressable, which is nested within a FlashList
• Pressable with unstable_pressDelay, delayLongPress, hitSlop & pressRetentionOffset props.
