Split examples, test and utils in their own BUILD.gn

The basic change was to copy-paste targets in the new BUILD.gn files and
fixup paths / add includes. There's a couple more changes that had to be
done at the same time:

 - Multiple files need to know if GLFW is supported so the variable was
moved to dawn_features.gni.
 - The gtest_and_gmock target used to abstract between Dawn's copy of
GTest/GMock is only needed by tests and was moved in src/tests/BUILD.gn.
 - A leftover dawn_end2end_tests target is left in the main BUILD.gn
file that is an exact copy of the on in src/tests/BUILD.gn. This is
because the GN path is hardcoded in Chromium's isolate_map.pyl that also
can't support GN groups. The only way to move a target I could figure
out was to duplicate it temporarily.
