Fix: Ensure ClearDefaultEventParameters is wrapped for internal SDK use

Corrects an issue in `analytics/src/swig/analytics.i` that caused a build failure (CS0117) because `FirebaseAnalyticsInternal.ClearDefaultEventParameters` was not being generated.

The problem was that `%ignore firebase::analytics::ClearDefaultEventParameters;` was preventing SWIG from wrapping this function, even though it was later declared in `analytics.i` with the intent to be wrapped for internal C# SDK use.

This commit removes the overly broad `%ignore` for `ClearDefaultEventParameters`. The function is now correctly wrapped by SWIG due to its explicit declaration in the SWIG interface file, making it available as `FirebaseAnalyticsInternal.ClearDefaultEventParameters()`. This allows `FirebaseAnalytics.SetDefaultParameters(null)` to call it as intended, without exposing `ClearDefaultEventParameters` as a new public API on `FirebaseAnalytics` itself.
