JDK-8266281: Assign Symbols to the package selector expression

[lahodaj]

The proposal in this patch is that package names in the package clause would be attributed with the appropriate PackageSymbols. So when using Trees.getElement on an AST node of some part of the package name, a sensible PackageSymbol would be returned.
