090e4113 - [CSDiag] Always find and set correct declaration context for sub-expression type-check

[CSDiag] Always find and set correct declaration context for sub-expression type-check Replace dedicated method with `typeCheckChildIndependently` always setting the closest possible declaration context for type-check call. This fixes a problem where sub-expression comes from multiple levels or nested closures but CSDiag didn't re-typecheck parent closure. Resolves: rdar://problem/50869732 (cherry picked from commit a5df7862636a303828cee724c6b779bc77280f65)
