Tag experimental API tests (#19811)

Add explicitly `-experimental -Yno-experimental` to tests that use
definitions that are `@experimental` in the standard library.
`-Yno-experimental` disables the experimental mode from nightly builds
and `-experimental` adds `@experimental` to all top-level definitions.

This is in preparation of #19760 and the disabling of experimental mode
by default in nightly builds. When nighly experimental mode will be
disabled we will be able to drop the `-Yno-experimental`.

These tests are for 
* `scala.annotation.MacroAnnotation`
* `scala.annotation.MainAnnotation`
* `scala.annotation.newMain`
* `scala.util.TupledFunction`
* Expreminetal definitions in `scala.quoted.Quotes`
