Rule request: minimal-namespace-depth

[JoshuaKGoldberg]

TypeScript code being linted

// File one
namespace A.B.C1 {
    export const D = 7;
}

// File two
namespace A.B.C2 {
    // Could also be referenced by C1.D
    const copy = A.B.C1.D;
}

Expected behavior

The A.B.C1.D reference is unnecessary long, which leads to bloated source files and bloated output code. It would be beneficial for folks still in namespace land to have a rule that blocks using unnecessarily prefixed namespace paths.

@andy-hanson does #2008 close this issue?

Yes, I mentioned this actually.
