  Log Message:
  -----------
  [clang][AST] TextNodeDumper should not evaluate the initializer of constexpr variable declaration when it has a dependent type

`TextNodeDumper` enabed through `-ast-dump` flag should not evlauate the initializer when it visits a constexpr `VarDecl` node if it has a dependent type.

I found a crashing case fixed by this change and added it as a test case.
`template <typename T> constexpr T call_init(0);`

This is a fix for the regression caused by D146358
