Propagate exceptions in napi_run_script

[190n]

What does this PR do?

Fixes napi_run_script to not swallow exceptions thrown by the eval'd script

How did you verify your code works?

Updated napi tests to cover napi_run_script in some edge cases + normal cases.

• I included a test for the new code, or existing tests cover it
• I ran my tests locally and they pass (bun-debug test test-file-name.test)
