📜 Description
removed the need of a transaction to start a profile in AndroidTransactionProfiler, allowing to bind one later
added a constructor to AndroidTransactionProfiler without options
added options as param to AndroidTransactionProfiler.onTransactionFinish
some cleanup in the profiler
💡 Motivation and Context
For the startup profiling feature, we need to create a profiler instance before the SDK is initialized, which means we don't have the options and cannot start any transaction, yet.
This change allows to create an instance of the profiler with only the parameters needed, without passing the whole SentryOptions object, and also allows to run the profiler before the transaction, and bind a transaction later on.
💚 How did you test it?
