Disable merged_trace_lite target in most configurations
The merged_trace_lite target is not really needed. We just build it to
make sure that the generated merged proto can be compiled as a C++ lite
proto.
The merged_trace_lite can take up to a couple of minutes to build with
optimizations. From a recent CI run:
```
[00:06:08] [3433/3437] link ./perfetto_integrationtests
[00:08:54] [3434/3437] compile gen/protos/perfetto/trace/perfetto_trace.pb.cc
[00:08:54] [3435/3437] stamp obj/protos/perfetto/trace/merged_trace_lite.stamp
```
Let's keep the target only on CI debug builds and remove it from
everything else (other CI builds, local dev builds and chromium builds,
which include every target).
