Initialize Recycler.INITIAL_CAPACITY before invoking InternalLogger.debug() (#10836)

Browse Source 
Motivation:

If Log4J2's `Filter` creates `Recycler.Stack` somehow, `Recycler.Stack()` will see uninitialized `Recycler.INITIAL_CAPACITY`. This has been raised originally in https://github.com/micrometer-metrics/micrometer/issues/2369.

Modification:

This PR changes to initialize `Recycler.INITIAL_CAPACITY` before invoking `InternalLogger.debug()` to avoid it.

Result:

Fixes the problem described in the "Motivation" section.
