[enhancement]: AzureFunctionApp task should validate appType against the existing function and enforce WEBSITE_RUN_FROM_PACKAGE settings accordingly

[domasd]

Task name

AzureFunctionApp@2

Describe your feature request here

Issue Description

The current implementation of the AzureFunctionApp task does not validate the appType (Linux or Windows) against the existing function, leading to potential silent issues when deploying functions with WEBSITE_RUN_FROM_PACKAGE settings. This can result in unexpected behavior, particularly when the WEBSITE_RUN_FROM_PACKAGE value is set to a URL.

Issue Context

• When WEBSITE_RUN_FROM_PACKAGE is set to a URL and the function app is on Windows, it may lead to trigger issues, causing the function to be unresponsive to requests without raising any exceptions.
• On Windows, the correct setting for WEBSITE_RUN_FROM_PACKAGE should be 1. However, if the appType is mistakenly selected as functionAppLinux, it can result in a frozen state without triggering, even when there are incoming requests.

Documentation Reference

WEBSITE_RUN_FROM_PACKAGE Documentation

Expected Behavior

The expected behavior is that if the task is used with appType: 'functionAppLinux' for a function on Windows, the task should fail and not proceed. This validation ensures that the deployment settings align with the platform requirements, preventing potential silent issues.
