Deprecate useDisposable

[saskliutas]

Changes

Deprecated useDisposable hook. It is not compatible with React 18 StrictMode and there is no way to make it work correctly without changing API. Updated useOptionalDisposable to work correctly. Made some changes to useDisposable hook to make it work in React 18 StrictMode as best as it can. Current implementation will leak some disposable resources in StrictMode but should work correctly when StrictMode is disabled.

Deprecated useTreeEventsHandler because it was based on useDisposable hook. Added new useControlledTreeEventsHandler hooks to replace it.

Testing

Ran modified tests in Presentation repo that uses useDisposable hook https://github.com/iTwin/presentation/blob/master/packages/components/src/test/hooks/UseRulesetRegistration.test.ts

I'd appreciate it if you'd add a PR number to changes in NextVersion.md while resolving the merge conflicts (i.e. #700)
