[SIEM] NP Plugin dependency cleanup (#64842)

* Remove static src dependencies from kibana.json

We are only importing static code from these plugins, and not consuming
their plugin contracts. For this reason, we can safely remove them from
kibana.json as that imported code will always be included in our own
bundle.

* Make usageCollection an optional dependency

If it's not enabled, we simply use a noop for our tracker call.

* Remove unused plugin contracts

These are only needed when we're actually using them in our codebase.
For request handler contexts, we only need our kibana.json declaration.

* Remove unnecessary try/catch

With the addition of the null coalescing, the only chance for an error
is in usageCollection. However, if the usageCollection contract changes,
we should get a type error long before we see a runtime error.

* Improve typings of our Plugin classes

* passes missing generic arguments to public plugin interface
* passes missing generic arguments to both plugins' CoreSetup types

* Don't re-export core types

Instead, import them from core as needed.
