Cherry-pick (#55283)

* Update SDK to 6.0 Preview 6

Part of #55281

* Enable COM support to work around missing symbols in tests

* Update eng/testing/linker/project.csproj.template

* Disable the workload targets

* Disable workloads for wasm builds

For in-tree builds, and tests we don't want to use workloads from dotnet
being used to build these.

For the projects being built on the build machine, we can disable them
via `Directory.Build.props`, and wasm's InTree/LocalBuild props. But for
projects that get built on helix, eg. the runtime tests, we are setting
the property values as environment variables.

* Fix setting envvars for disabling workloads

* Another attempt to fix wasm tests

In preview5, the workload manifest overrides
`$(UsingBrowserRuntimeWorkload)` setting, so pass it on the command
line.

``xml
    <PropertyGroup Condition="'$(RuntimeIdentifier)' == 'browser-wasm'">
        <UsingBrowserRuntimeWorkload Condition="'$(RunAOTCompilation)' == 'true' or '$(UsingMicrosoftNETSdkBlazorWebAssembly)' != 'true'" >true</UsingBrowserRuntimeWorkload>
        <UsingBrowserRuntimeWorkload Condition="'$(UsingBrowserRuntimeWorkload)' == ''" >$(WasmNativeWorkload)</UsingBrowserRuntimeWorkload>
    </PropertyGroup>
```

* Fix host tests after upgrade to P5

In P5 we don't generate .runtimeconfig.dev.json anymore. Some tests started to fail because they relied on the .runtime.dev.json to include local nuget cache in the probing paths.

I changed one of those tests to force-generate .runtimeconfig.dev.json as for the tested scenario it seems to make sense. For the other test I modified it to copy the necessary dependency into the right location instead.

* Fix up reflection to private FileStatus field

* Disable workload resolver for wasm.build.tests, EMSDK run

* Disable workloads for wasm with MSBuildEnableWorkloadResolver=false everywhere

* remove linker workaround

* [wasm] Remove args unnecessary for disabling workloads

* Pass MSBuildEnableWorkloadResolver property to individual trimming projects
