  [clang][ASTImporter] Fix crash when import `VarTemplateDecl` in record (#67522)

[clang][ASTImporter] Fix crash when import `VarTemplateDecl` in record
static VarTemplateDecl in record isn't a definition, when imported
before, it will crash in `ASTContext::setTemplateOrSpecializationInfo`
due to setting specialization while it already exists. This patch skip
this specific case.
