  -----------
  [clang][StaticAnalyzer] Add support for variables and fields in GetEnclosingDeclContextSignature

Function `getIssueHash` relies on the name of the enclosing
declaration of the issue Decl for hashing. But the underlying
function `GetEnclosingDeclContextSignature` does not compute the
enclosing declaration for variables or fields, causing missing HTML
reports despite text warnings being printed.

The added
`clang/test/Analysis/Checkers/WebKit/html-diag-dedup-members.cpp`
example is a reproducer of this kind of issue we observed in WebKit.

Also, `RawPtrRefLocalVarsChecker` and `RawPtrRefMemberChecker` never
called `Report->setDeclWithIssue()`. This commit fixes it.
