  [flang] Retrieve shape from selector when generating assoc sym type (#137117)

This PR extends `genSymbolType` so that the type of an associating
symbol carries the shape of the selector expression, if any. This is a
fix for a bug that triggered when an associating symbol is used in a
locality specifier. For example, given the following input:

```fortran
  associate(a => aa(4:))
    do concurrent (i = 4:11) local(a)
      a(i) = 0
    end do
  end associate
```
before the changes in the PR, flang would assert that we are casting
between incompatible types. The issue happened since for the associating
symbol (`a`), flang generated its type as `f32` rather than
`!fir.array<8xf32>` as it should be in this case.
