[mono-api-html] Improve attribute handling.

[rolfbjarne]

• Simplify and expand how custom attributes are written into the xml description
  by not doing any fancy computation about the attribute properties, instead just
  write out what's in IL: any constructor arguments + parameter arguments.
• Compare and show attributes for types and members.
• Special-case [Experimental] attributes:
  • Adding an [Experimental] attribute to an existing type/member is a breaking change.
  • If a type or a member has an [Experimental] attribute, no changes within are breaking.
• Removal of an obsolete type/member is a breaking change, so show it as such.
