ManagedToNativeGenerator is invoked on every build

[AdmiralSnyder]

Description

ManagedToNativeGenerator in WasmApp.Common.targets is called too often, even if no source code changed.

this results a) in a time loss when building or hitting F5 in VS and
b) in my case lots of unnecessary warnings obscuring actual warnings:

Reproduction Steps

create a blazor wasm project
run dotnet build -bl
run dotnet build -bl a second time without modifying files in between runs
, inspect the binlog
, observe that ManagedToNativeGenerator is there, eating up time unnecessarily

here's my .csproj:

SAK SAK SAK SAK $(CODie__DotNetVersion) true Default service-worker-assets.js

Expected behavior

this should only run when something has actually changed in the inputs

Actual behavior

it runs on every build
