parser should be able to resolve array type that uses imported types

**Describe the bug**

Seems like dslx_fmt (and the parser?) don't manage to resolve array type that uses imported types.

**To Reproduce**

the following expression:
```
float32::F32[2][3]:[
[float32::one(), float32::zero(u1:0)],
[float32::one(), float32::zero(u1:0)],
[float32::one(), float32::zero(u1:0)],
]
```
will produces this error:
```
Type before ':' for presumed array literal was not a type definition; got `float32::F32[2]

```

**Workaround**

alias the type locally w/
```
type F32 = float32::F32;
```
and use:
```
F32[2][3]:[
[float32::one(), float32::zero(u1:0)],
[float32::one(), float32::zero(u1:0)],
[float32::one(), float32::zero(u1:0)],
]
```
