docs(apple): Add missing experimental options and remove experimental-features page (#17987)

## DESCRIBE YOUR PR

Add missing `<SdkOption>` entries for
`experimental.enableUnhandledCPPExceptionsV2` and
`experimental.enableWatchdogTerminationsV2` to the Apple SDK options
reference.

Remove the standalone `experimental-features.mdx` page since all its
content is now covered in `options.mdx` or on the pages it linked to
(some of which were broken links to features removed in SDK 9.0.0).

- Add `experimental.enableUnhandledCPPExceptionsV2` option to
`options.mdx`
- Add `experimental.enableWatchdogTerminationsV2` option to
`options.mdx`
- Delete
`docs/platforms/apple/common/features/experimental-features.mdx`
- Remove references to the deleted page from features index pages
(common, macOS, visionOS)
