…ng (#120746)

Backport of #120694 to release/10.0

In dotnet/sdk#50949 we changed the identity of
StaticWebAsset to contain fingerprint (dotnet.native.wasm ->
dotnet.native.FP.wasm). This PR accommodates this when checking for
dotnet.native.wasm asset from build.

The SDK change didn't flown to the runtime yet, and so Wasm.Build.Tests
won't test it yet.

Fixes dotnet/aspnetcore#64011

Introduced in dotnet/sdk#50949 which added a
fingerprint to the msbuild item identity

## Testing

Manual and automated tests.

## Risk

Low. The change are very scoped to target and items used only by
preloading.

**IMPORTANT**: If this backport is for a servicing release, please
verify that:

- The PR target branch is `release/X.0-staging`, not `release/X.0`.

## Package authoring no longer needed in .NET 9

**IMPORTANT**: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.
