refact(TVOS): using common example src

[alduzy]

Description

This PR intents to use common examples src directory in TVOS Example app.

The example screens that were removed with tvos specific src folder are all present in the common directory in similar or slightly more complex shape ready to be tested.

Some of the common examples that are being exposed to TVOS by this PR are not working properly as they were not intended to work on TV platform, those are:

• swipe back animation screen (working well, but without the gesture)
• animations playground
• status bar playground
• orientation playground
• search bar playground
• gestures playground
  I decided to filter them out for TV devices.

There are also some issues worth pointing out I found while playing around with the TVOS example:

• header text and background colors are unchangeable (white on light grey in regular screens and gray on dark gray in modals)
• the value in the input is not visible until the input is hovered or focused (try it in Stack Presentation -> formSheet)
• select inputs are not selectable - just expandable, thus not accessible (try it in header options playground)

Changes

• removed TVOS src directory
• linked apps/examples/App in TVOS App.tsx
• added TVOS Platform ternary in common App.tsx file
