Adding apex_defaults to provide common parameters for Q, R, S and T.

This CL is adding the apex_defaults modules to provide common
parameters for the releases corresponding to Q, R, S and T.

These defaults servers as a common place to add properties which should
affect all mainline modules.

Bug: 172589606
Test: USE_RBE=true m
Since there are no runtime changes, successful code build is enough for
testing.
