Add support for BoundedArray

[evyatark2]

I couldn't figure out the best way to detect a BoundedArray since it is not a type but a type constructor.

The way I go about it is to check if the struct "looks like" one (has a buffer field) and then we take the length of the array of the buffer field and construct a BoundedArray(u8, array_len) and check if it is the same type.

@evyatark2 That is less explicit and may not only strictly refers to std.BoundedArray, I'd prefer to use @typeName, and check if it starts with or contains std.BoundedArray.

That was my initial approach.

Wouldn't @typeName return zig.BoundedArray if the user decides to use const zig = @import("std");

As for the strictly referring to BoundedArray it does do that but only on the line if (FieldType == std.BoundedArray(u8, array.len)) after we check initially that it is potentially it.

Oh, I see what you mean, I guess this is fine. I don't have issue with implementing this way.
