`column_major` and `row_major` don't apply correctly to template-dependent types

This is caused by the same issue as #4583, so the required transformation is similar.

This test case should cover the interesting cases:

// RUN: %clang_cc1 -HV 2021 -fsyntax-only -ffreestanding -verify %s

template <typename T, int X, int Y>
struct Matrices {
  row_major matrix<T, X, Y> RowMajor;
  column_major matrix<T, X, Y> RowMajor;

  row_major T NotAMatrix;        // expected-error {{'row_major' can only be used with a matrix type}}
  column_major T AlsoNotAMatrix; // expected-error {{'column_major' can only be used with a matrix type}}
};

struct AlsoMatrices {
  row_major matrix<float, 4, 4> RowMajor;
  column_major matrix<float, 4, 4> RowMajor;

  row_major float NotAMatrix;        // expected-error {{'row_major' can only be used with a matrix type}}
  column_major float AlsoNotAMatrix; // expected-error {{'column_major' can only be used with a matrix type}}
};

void fn() {
  Matrices<float, 4, 4> ShouldWork;
}

Start by comparing the template-dependent matrix declarations in this issue with the required transformation described in #4583. Run the provided clang_cc1 test case with -HV 2021 and -verify; done means the matrix qualifiers work for dependent types while the non-matrix declarations produce the shown diagnostics.
