@typeInfo returns private decls even when T is external

Zig Version

0.10.0-dev.477+aa902c704

Steps to Reproduce

const std = @import("std");
const other = @import("./other.zig");

test {
    const ti = @typeInfo(other);
    const decls = ti.Struct.decls;

    try std.testing.expectEqual(2, decls.len);
    try std.testing.expectEqualStrings("Enum", decls[0].name);
    try std.testing.expectEqualStrings("Struct", decls[1].name);
}

const std = @import("std");

pub const Enum = enum {
    a,
    b,
    c,
};

pub const Struct = struct {
    foo: i32,
};

Expected Behavior

All 1 tests passed.

Actual Behavior

Test [0/1] test ""... expected 2, found 3
Test [1/1] test ""... FAIL (TestExpectedEqual)

[andrewrk]

Intended behavior is for @typeInfo to always return only public decls, no matter where the callsite of @typeInfo is.

[g-w1]

I made a breaking change to the language in #16547 , (removing is_pub), but this seems warranted because only public decls are allowed in @typeInfo.
