[FEATURE] 📜 Add `WithoutLogger()` method to Builder

[jodydonetti]

Problem

As pointed out in a community discussion, it would be nice to have a WithoutLogger() method available for the builder, so to disable logging completely.

The default behavior is to use the one registered in the DI container, if any.

Solution

Add a new WithoutLogger() method that does noy use any logger at all.

Alternatives

It is possible to use WithLogger(NullLogger<FusionCache>.Instance) but, although technically correct, that feels cumbersome.
