Reland "skia: Add 'skia_unittests' test suite for this directory."

This should be a lightweight test suite that should allow a dev changing
something in skia/ext to test it much more quickly than having to build
all 'unit_tests' target just to run the tests from skia/ext.

It was reverted because it broke Mac GN with error like:
duplicate symbol __ZN3gfx27SkMatrixToCGAffineTransformERK8SkMatrix in:
    obj/skia/ext/skia_unittests.skia_utils_mac_unittest.o
        obj/skia/ext/skia.skia_utils_mac.o
        (and more similar issues).

BUG=444058
TEST=skia_unittests links and runs fine.
R=danakj@chromium.org,thakis@chromium.org,glider@chromium.org,sky@chromium.org
TBR=glider@chromium.org (already reviewed tools/valgrind - and no changes were made at that directory).
