Multiple filter invocations in `AsyncLoggerConfig`

[ppkarwasz]

Description

The AsyncLoggerConfig calls AbstractFilterable#isFiltered(LogEvent) three times:

• twice on the calling thread (for asynchronous and synchronous dispatch),
• once on the logging thread.

While this is not a problem per se, this causes unnecessary problems to stateful filters like in micrometer-metrics/micrometer#2176.
