fix: duplicate query parameters fail validation if one of the paramaters is a list

[cstarkers]

Description

Allow a single query parameter to be aliased to multiple Python parameters, even when one of the Python parameters is a list.

Previously, if a query paramater was remapped to multiple different Python paramenters by using Parameter(query="alias") and one of the Python parameters was a list, a validation error was raised. This was inconsisent with how non-list query parameters worked.

Fixes #4242

Looks good in general, but I think this should take into account header parameters as well. The same semantics should apply there as well

Cool, done now

I also refactored some stuff as MultiDict, which I can imagine having a perf impact (probably positive, Multidict should be fast, but who knows, it could be negative)

Is there a performance testing suite/metrics for Litestar?
