Full build and testing directly from CMake (#6393)

Add a direct mode for CMake builds. Add a CMake variable to distinguish
between `build.sh` and direct command line use -- in direct mode the
build would try to pick up reasonable system defaults. Set that variable
to OFF by default and to ON in `build.sh`.

Add explicit option for Intl support for direct CMake use and set its
default to `ON`. Add another explicit option for ICU include path
(default to empty), also only under direct CMake. Make sure Intl setting
does not get overridden.

Expose some ICU build options - embedding (default to OFF), Intl
(default to ON), and ICU include path (default to empty).

Move DbgController.js.h generation to CMake, make that step conditional
on whether dependencies have changed.

Add testing under control of CMake. Invoking `check` target should
run entire test suite, producing log file in the build directory.
Exclude tests dependent on ICU for non-ICU builds.

Make some CMake error messages slightly more informative.

Nit: build.sh - "makefiles" is inaccurate, as it supports Ninja as well.

Closes #6417
