[BUG] iOS tv-casting-app:

[sharadb-amazon]

Reproduction steps

The Matter SDK assumes that the client will take a lock on the SDK prior to interacting with any APIs. There is 1 Android function and several iOS functions that do not take the lock prior to interacting with the SDK APIs.

There are also some functions that invoke the Matter SDK in a way that may result in out-of-order callback invocation (e.g. the conceptual "started" callback may be invoked after the conceptual "ended" callback).

Without the StackLocks we see that the iOS tv-casting-app can crash or show unexpected behaviour when calling the Matter SDK APIs.
