refactor!: Improve strict search

[angelobreuer]

This PR will solve various problems that were present with the old strict search solution. The default will stay to be the most pedantic option (Throw) which will fail if Lavalink4NET recognizes an attempt of the user trying to specify a search mode. However, this option also flagged search queries like PR: abc which may be valid search queries for some tracks. The option Resolve solves this problem by prepending the search prefix to those queries.

Please read the documentation of StrictSearchBehavior to learn more about the various new behaviors.

For users that previously enabled or disabled strict search, the option Throw matches the exact behavior as previously when strict search was enabled. The Passthrough options most likely matches the behavior as when strict search was disabled.
