Diagnose `@derivative` and `@transpose` attributes that are missing the
required comma before the `wrt:` clause:
```
@derivative(of: foo wrt: x)
@transpose(of: bar wrt: (x, y))
```
Previously, this was undiagnosed.
Resolves TF-1168.
The `@transpose(of:)` attribute registers a function as a transpose of another
function. This patch adds the `@transpose(of:)` attribute definition, syntax,
parsing, and printing.
Resolves TF-827.
Todos:
- Type-checking (TF-830, TF-1060).
- Enable serialization (TF-838).
- Use module-qualified names instead of custom qualified name syntax/parsing
(TF-1066).
The `@derivative(of:)` attribute registers a function as a derivative of another
