Deprecate `beforeSendTransaction` and `ignoreTransactions` and log warnings if used with span streaming enabled

[Lms24]

With span streaming enabled by default, beforeSendTranasaction and ignoreTransactions are ignored by the SDK and thus not applied anymore. It's easy to miss though when upgrading. To mitigate this, we:

1. deprecate the two options with a note stating that they'll be removed in v12, and until then can only be used in conjunction with traceLifecycle: 'Static'. Otherwise, they have no effect and will be ignored by the SDK.
2. log a console warning (bypassing our debug logger), in case users still have these options defined.
