fix CoCo error 0x10AA1 - imported and quoted PartDef resolution

[linggd]

The Apollo-11 models can already be parsed #146 . The symbol resolution and CoCos are adapted so that the models also pass the CoCos.

2 of 5 CoCo errors addressed

0x10AA1 — PartDef resolution

Apollo introduced several cases that were not covered by the previous models:

• PartUsages with both : typing and :> specialization. The CoCo incorrectly checked both as PartDefs.,
• Imported PartDefs. Import-aware resolution existed for resolveType(), but not for resolvePartDef().,
• Imports declared in the current package scope. The existing logic only checked the enclosing scope and therefore missed these imports.,
• Quoted names containing dots, such as 'Roger B. Chaffee'. The dots were incorrectly interpreted as qualification separators.,

These cases exposed missing or incorrect behavior in the PartDef resolution.

Changelog

Fix

• Override continuePartDefWithEnclosingScope() and add import-aware PartDef resolution.
• Collect imports from the current scope before continuing resolution in the enclosing scope.
• Check only ASTSysMLTyping, which represents the actual type introduced by :.
• Added support for quoted PartDef names containing dots, by resolving the imported package and matching the complete local symbol name.
