zephyr: zmake: Drop common cmake and ninja messages

When ninja gets an error it reports that the build stops, but we know
that since we see the error and get a return code. Move it to DEBUG.

Similarly cmake shows FAILED which is not useful since we can see the
actual error immediately above, so move it to INFO.

Also it prints out the command that failed but this is normally just a
20-line compiler invocation command which is not actionable and makes
it easy to miss the one-line, useful error from the compiler. Move
that to DEBUG.

BUG=b:177096315
BRANCH=none
TEST=manually test by running zmake build / configure
