Fixing Bulk codefix (Removed unused opens) + adding new ones in Bulk mode

[T-Gro]

The following fixes are now available in bulk document/project/solution mode.
The selection was done subjectively my thinking which kind of diagnostical errors can easily accumulate over a codebase (e.g. after a refactoring, or when updating language version) and where the benefit of a bulk fix exists.

There is no guarantee that other codefixes wouldnt benefit from bulk mode massively as well - if you think of any, let me know and such can be added later as well.

• Add "new" when creating IDisposable types
• Changing .[] indexer into dot-less []
• Removing superflous "_" capture for union case with no data
• Removing unused binding
• Renaming unused binding with _
• Prefixing unused binding with _
• Renaming parameter names in .fs files to match signature files
• Name simplification (if namespace/module is open, reducing the FQ path) => the analyzer itself is not working to its full potential now, I am addressing this in a separate PR.

Telemetry reporting in it's previous form would not work for the bulk operation.
The codefixers have explicit telemetry reporting, on the level of 1 event per document in bulk operatios (as opposed to 1 event per each occurrence normally)
