Add support for indexing UI5 XML views

[lcartey]

This PR adds support to our JavaScript extractor hook to automatically index UI5 XML views.

Per the documentation all such views should end with the suffix .view.xml, so we do not need to consider the contents when determining what to index.

In addition to this PR, I have also opened a PR on github/codeql to ensure the following relevant UI5 and XSJS .json files are indexed:

• *.view.json
• xs-app.json
• manifest.json

We document this in the post-finalize.sh hook to ensure it's clear where this happens.

@jeongsoolee09 can you please confirm that after these changes we would now capture all relevant CAP, UI5 and XSJS files during extraction?

Yes, with the three file patterns we're capturing all of the data formats used by our queries. There's another special file called XS Application descriptor with name .xsapp (example) that is a JSON in disguise much like .xsaccess. However, it's irrelevant to our queries and can be ignored.
