Added single-file distributions of Tcl for all main platforms.

These are *UNOFFICIAL* builds as they do not correspond to particular releases.

The macOS build is packaged in a .dmg with a README that explains how to run it
as the binary is not signed or notarized (and this is unlikely to change).
