[Feature] In-line Struct Assignment

[anantajit]

As I understand the current Veryl documentation, struct assignment in Veryl cannot be done in-line and each field must be initialized separately:

struct X {
  field_1: ...,
  field_2: ...
}

...

var x: X;
x.field_1 = ...
x.field_2 = ...

I think that the following Rust-like syntax would be best for this use-case:

let x = X { field_1: ..., field_2: ... };
