Add entryPointBaseUrl support for web workers 

Introduces the entryPointBaseUrl property to configuration in index.html and flutter_bootstrap.js, and updates python.js to use this base URL when creating Python web workers. This change allows for more flexible deployment scenarios where the entry point base URL may differ.
