DebugInfo: Remove DIDescriptor from the DIBuilder API

Description

DebugInfo: Remove DIDescriptor from the DIBuilder API

As a step toward killing DIDescriptor and its subclasses, remove it
from the DIBuilder API. Replace the subclasses with appropriate
pointers from the new debug info hierarchy. There are a couple of
possible surprises in type choices for out-of-tree frontends:

  • Subroutine types: MDSubroutineType, not MDCompositeTypeBase.
  • Composite types: MDCompositeType, not MDCompositeTypeBase.
  • Scopes: MDScope, not MDNode.
  • Generic debug info nodes: DebugNode, not MDNode.

This is part of PR23080.
