  [clang][ASTImporter] Propagate TemplateArgument::IsDefaulted during import

With https://reviews.llvm.org/D141826 `TemplateArgument`s have an
additional field that indicates their defaulted-ness. This gets
used during debug-info generation and in the `clang::TypePrinter`.

This patch copies the field during the import process so consumers
of the ASTImporter can benefit from the other Clang components that
read the field.

**Testing**

* Added unit-test
* Checked that this fixes (in addition to a follow-up LLDB patch)
  fix current test failures in LLDB

  Log Message:
  -----------
  [lldb][CXXModuleHandler] Set TemplateArgument::IsDefaulted

Since https://reviews.llvm.org/D141827 this field gets used
to print type names. Thus propagate it after importing TemplateArguments
from modules.

**Testing**

* Confirmed that this fixes the ongoing `import-std-module` test
  failures.
