extensions/ext: Rename debug_utils_set_object_name to set_debug_utils_object_name and debug_utils_set_object_tag to set_debug_utils_object_tag for consistency and deprecate old ones

Fixes #660

Can you fix the title of this PR, add a changelog entry, and target 0.37-stable? For the master branch I'd remove the offending function entirely.

[MarijnS95]

For the deprecation message, vk.xml uses the following: Backwards-compatible alias containing a typo. We don't need to use that, but something like it has my preference. I.e. Backwards-compatible alias containing a typo, use <the right function name> instead.

Also, can you double-check if intradoc links in deprecation messages now work?

Even after fixing the reference (must be prefixed by Self:: or DebugUtils::) they still don't work:

Can you remove the [] link brackets around it, and add () at the end of the name?

@BeastLe9enD Also, after targeting 0.37-stable feel free to submit a new PR removing the functions entirely for master (with appropriate changelog item). I'll sort out the changelog on master when we eventually perform a 0.37 release.

[MarijnS95]

Since this hasn't been rebased on 0.37-stable (only the target branch was updated) I'll cherry-pick it to that branch (like I do with any other PR for now, however inconvenient that workflow may be) and push a commit to master that removes the deprecated functions entirely.
