[3.0] Improve handling of affixed names when singularizing (OES/SGIS issue) and expose NameAffix API

[Exanite]

Summary of the PR

This fixes the interaction between Khronos vendor suffixes and the Singularize method, which led to cases like the following:

In order to fix this, this also exposes the NameAffix API, allowing mods to read NameAffix attributes and process the name without the affixes attached.

Further Comments

Todo list:

• Prevent OES and similar from being singularizing into O in ArrayParameterTransformer.TransformArrayParameterRewriter.
  • Eg: glFeedbackBufferxOES
  • Discussed solution is to expose the name affix API so that TransformArrayParameterRewriter can singularize the base name instead of the full name.
  • OES (incorrect version is OOES)
  • SGIS (incorrect version is SgiSGIS)
• Allow mods to read NameAffix data.
• Allow mods to strip a name of its affixes
• Allow mods to re-apply a list of affixes to the name, but without allowing mods to deeply configure the process
  • Reasoning is that more involved transformations should be restricted to PrettifyNames.
  • This is because PrettifyNames can be configured by the generator user, while other mods must expose their own (possible duplicate) configuration.
• Consider updating AddNameAffix API to use the new NameAffixType enum for consistency and simplicity
