Font size adjustment needed an override for the key preview to prevent
it using the base key font size as a starting point.

Fixes #5929.
Fixes #6381.

This fixes four separate issues with the longpress popups and key
previews:

1. The key preview was offset by a couple of pixels (unreported issue).
2. The background 'shim' did not cover the key caps, which caused them
   to look startlingly white when the rest of the background greyed
   down (#5929).
3. The popup menu was incorrectly wrapping to two rows due to sizing
   model mismatches (#6381).
4. The popup menu would be realigned incorrectly for the in-app
   keyboard, when moving it to keep it in the keyboard area (#5929).

When embedding the On Screen Keyboard into a page, the calculation for
the bounding rectangle only took into account the first offsetParent,
which meant it would get the offset incorrect when there were multiple
layers of offsetParents.

Once I changed to using getAbsoluteX / getAbsoluteY, this also corrects
for scroll with window.pageOffsetY, so we can eliminate that special
case for fixed positioning.

This was observable in the Web Developer test window, where interaction
with the bottom row of the keyboard in touch mode was not working
correctly, in 15.0.210-beta.

feat(common): build test keyboards via script

Some of the global color variables in shellHelperFunctions.sh were a
little dangerously named. This cleans that up and removes a couple of
redundant functions from other locations.

mac/bashHelperFunctions.sh should be removed and replaced with
references to shellHelperFunctions.sh -- but I wanted to leave that for
a separate branch.

Relates to #5815.

build.sh is a new script that builds any or all of the keyboards in the
common/test/keyboards folder. build.bat is a wrapper for build.sh, just
for Windows CMD.

Assumes that kmcomp.exe has already been built or allows you to specify
your own kmcomp.exe if necessary.

chore(linux): Debug why Beta build didn't get triggered

Co-authored-by: Marc Durdin <marc@durdin.net>

This change adds temporary debug code to track down why the beta
build didn't get triggered by outputting the OUTPUT string.
It also counts the lines we're outputting so that we can output
a newline in case we're not outputting anything.
