[iOS][code coverage] Enable code coverage in iOS CQ builders.

After this CL coverage data from tests in these builders will surface
in Gerrit. Changed try builders configs and test configs to enable it on
the 2 iOS CQ builders.

In order to pass CQ, this change includes builder and test configs. GN
config change is in crrev/c/2566333 and will be landed right after.
