Subject: Fix entry overrides in support matrix generation

Fix #2539

The entries in the board's mpconfigboard.mk override any other entries.

Also, fixed a warning for bad use of backslash in a string.

Subject: shared_bindings_matrix: Work from parsed 'make' output

Revisiting this because I noticed the support matrix said that pyruler
had several modules it obviously didn't, such as the recently added
vectorio.

It is less error-prone because we can use the final values instead
of re-coding the Makefile logic in python.  The only things we need
to do are invoke make in "print-database" mode, then chase any
indirect references like CIRCUITPY_VECTORIO = $(CIRCUITPY_DISPLAYIO)

It does take longer, about 45s on my laptop.

Not sure why I moved it, the computed value is never required

Subject: shared_bindings_matrix: Use a trivial target

Sommersoft noticed that without submodules (as RTD currently does),
the "make -qp" failed due to trying to find files within submodules.

The "print-VAR" target doesn't have any dependencies, so it sidesteps
the problem.

If we move ulab's pyi files into the submodule, though, we'll need to
fetch submodules anyway during doc building.
