Compile time calculation generates types lacks type hints and code completion.

For example, the following code:

const std = @import("std");

pub fn foo() void {
    std.debug.print("Hello World!", .{});
}

pub fn main() !void {
    const p = &foo;

    const T = @Type(.{ .@"struct" = .{
        .fields = &.{
            std.builtin.Type.StructField{
                .name = "foo",
                .is_comptime = false,
                .type = *const @TypeOf(foo),
                .alignment = 4,
                .default_value_ptr = @ptrCast(&p),
            },
        },
        .decls = &.{},
        .is_tuple = false,
        .layout = .auto,
    } });

    const a = T{};
    a.foo();
}

The effect in VSCode is as follows:

The instances of type T and T generated during compilation in the code have no type hints and code completion.
