Fix Blazor WASM SWA test failures

[javiercn]

Fixes #53791

This PR fixes all static web assets related Blazor WASM test failures:

• Removed Skip attributes from 13 tests across BlazorWasmStaticWebAssetsIntegrationTest, WasmJsModulesIntegrationTests, and WasmPublishIntegrationTest
• Fixed BlazorWasmReferencedByAspNetCoreServer test asset — replaced hardcoded net11.0 TFM and stale 10.0.0-rc.1.25451.107 package versions with $(AspNetTestTfm) / Version="5.0.0", and simplified Client/Server code to use 5.0-compatible APIs
• Fixed Publish_WithTrimmingdDisabled_Works — Microsoft.Extensions.Logging.Abstractions.wasm no longer exists in .NET 11 (merged into Microsoft.Extensions.Logging); updated the assertion accordingly
• Regenerated stale baselines for compressed asset changes in .NET 11

Pull request overview

This PR addresses Blazor WebAssembly static web assets test failures by updating test assets and expectations to match current framework packaging/output, and by re-enabling previously skipped tests once baselines are refreshed.

Changes:

• Re-enabled multiple previously skipped Blazor WASM SWA tests gated by MSBuild version requirements.
• Updated the BlazorWasmReferencedByAspNetCoreServer test asset to use $(AspNetTestTfm) and refreshed ASP.NET Core package references + hosting code paths.
• Regenerated/updated static web assets baselines to reflect current compressed asset/assembly outputs (including removed/merged assemblies).
