Add PHP QueryParameter import after property renaming

[AayushP123]

Summary

Evaluates the PHP QueryParameter import after query property names are normalized. Adds regression coverage for snake_case query parameters that become camelCase while retaining their serialization name.

The import evaluator previously ran before ReplacePropertyNames populated SerializationName, so generated annotations could be emitted without the corresponding import.

Validation

dotnet test tests/Kiota.Builder.Tests/Kiota.Builder.Tests.csproj --no-restore --nologo --filter 'FullyQualifiedName~Refiners.PhpLanguageRefinerTests' (14 passed)

Fixes #7602

Pull request overview

This PR fixes a PHP generation bug where the @QueryParameter("...") docblock annotation could be emitted without importing Microsoft\Kiota\Abstractions\QueryParameter when query parameter property names are normalized (e.g., snake_case → camelCase). It adjusts the PHP refiner’s import evaluation order so the import decision occurs after SerializationName is populated, and adds a regression test for the scenario reported in #7602.

Changes:

• Run an additional PHP default-import evaluation pass specifically for QueryParameter after ReplacePropertyNames has set SerializationName.
• Refactor the QueryParameter import evaluator into a dedicated evaluator list to ensure it’s applied at the correct stage.
• Add a regression test validating both the renaming (category_id → categoryId) and the presence of the QueryParameter import.
