Rob Findley c6531fae58 go/types,types2: avoid data race to object.color_ through dot imports 
As described in issue #69912, type checking dot-imported identifiers can
result in a call to objDecl on an imported object, which leads to a data
race to the color_ field.

There are multiple potential fixes for this race. Opt for avoiding the
call to objDecl altogether, rather than setting color_ during import.
The color_ field is an internal property of objects that should only be
valid during the type checking of their package. We should not be
calling objDecl on imported objects.

Fixes #69912
