zephyr: Generate initial coverage for every board
Create a new ninja target 'all.libraries' which is everything that
zephyr.elf depends on, but doesn't actually link the zephyr.elf binary.
This allows creating coverage info for boards that run on SOCs that are
too small for real coverage runs.
Enabled the HAS_COVERAGE_SUPPORT for all boards, so that the
all.libraries target will build with coverage enabled.
HAS_COVERAGE_SUPPORT can't be set in prj files, as it is not directly
user assignable. This is probably somewhat of a misuse of this flag, but
nothing depends on it except for CONFIG_COVERAGE.
Tweaked the instructions to exclude some more directories that are not
useful code, like tests and generate headers.
