Previously, the DeclID is defined in serialization/ASTBitCodes.h under clang::serialization namespace. However, actually the DeclID is not purely used in serialization part. The DeclID is already widely used in AST and all around the clang project via classes like `LazyPtrDecl` or calling `ExternalASTSource::getExernalDecl()`. All such uses are via the raw underlying type of `DeclID` as `uint32_t`. This is not pretty good. This patch moves the DeclID class family to a new header `AST/DeclID.h` so that the whole project can use the wrapped class `DeclID`, `GlobalDeclID` and `LocalDeclID` instead of the raw underlying type. This can improve the readability and the type safety.
