A few long-standing Tk commands have no tkinter wrapper and are currently reachable only through tk.call().

• The menu postcascade command (since Tk 8.5) posts the submenu of a cascade entry, complementing the already wrapped post and unpost.
• tk scaling (since Tk 8.4) queries or sets the scaling factor (pixels per point) used to convert between physical units and pixels.
• tk inactive (since Tk 8.5) returns the time in milliseconds since the user last interacted with the system, and can reset that timer.

I propose to add the corresponding Menu.postcascade(), Misc.tk_scaling() and Misc.tk_inactive() methods.

   The AMD64 Windows11 buildbot fails test_tk_inactive: assertGreaterEqual(ms, -1) got -2137503217.

   This is a Windows-only Tk bug: Tk_GetUserInactiveTime() returns a C long, which is only 32-bit there, so a long inactivity interval (as on a non-interactive session) overflows to a negative value. Reported upstream as Tk ticket 3cb7c4ac72d4.

   PR #152683 guards the check on Windows pending the Tk fix.
