Adds support for the track series to the client-side hook
implementation.

Adds hook support in browser contract tests as well as adding the
`track-hooks` capability.

#830)

**Requirements**

- [x] I have added test coverage for new or changed functionality
- [x] I have followed the repository's [pull request submission
guidelines](../blob/main/CONTRIBUTING.md#submitting-pull-requests)
- [ ] I have validated my changes against all supported platform
versions
Classes are independent of platforms for the moment, and also not
reachable. (Except for Backoff which was moved).

This PR moves shared/common changes for FDv2 from the temporary holding
branch to main. All code has been previously reviewed and was picked
from the temporary holding branch using file pick commands.

Additional prettier fix commits.

Wrappers are accessed through the platform, but react-native and the
browser implementation were not propagating these to the platform.

The first implementation was the node platform, which handled this
correctly. The Cloudlare and RN platform didn't, and then the RN
platform was used as reference for implementing the browser platform.

So, this also affects edge and a similar update should be considered for
those SDKs.

Adds plugin support for react native and browser.

Types are common, as well as most functionality, but SDK specific
implementation is required. This is because the leaf-node SDKs have
different types for the LDClient. Also the SDK needs control over the
ordering of operations that happen during construction in order to
register plugins at the correct point.

There is a bit more complexity in this implementation than would be
required for most SDKs. Some refactoring of the base client
implementation, potentially to use composition instead of inheritance,
may allow for some better sharing here in the long-term.

Initially I tried using generics in the base implementation, to account
for the different client implementations, but this introduced a lot of
changes to all the layers and didn't play well with configuration, which
also then needs to be generic.

The approach I took was to have the configuration in the individual SDKs
and then use generics for utility methods to collect hooks and register
plugins. In the long-term this would also benefit from the base
implementation using generics for the configuration, which would allow a
shared configuration and validation.
