Fix running WebAssembly Browser App from VS (#75384)

Fix running WebAssembly Browser App from VS (#75384)

* trying to fix 75356

* Trying to fix for running from VS and from command line

* Remove unused spaces

* Fix again

* Addressing @radical comments

* OutputPath can be missing the rid during the evaluation

* more cleanup

* Replacing NormalizeDirectory with  [System.IO.Path]::Combine

* [wasm] Add tests for running templates outside project directory

* Add tests for browser template

* Disable failing test

.. which is failing because the WBT is still using net7.0 on `main`,
thus using the 7.0 targets, which don't have the fix yet.

We can enable this once the fix is merged for 7.0 .
