Turn deps of chromium_builder_perf into data_deps.

It seems that for "group" labels GN does not include data of dependencies
declared as "deps", but it would be convenient if we could refer to
chromium_builder_perf group to query all the runtime dependencies of the
test binaries.  This change does not touch dependency logic, though: all
the prerequisites of chromium_builder_perf continue to build as before.

The runtime_deps of this target can then be used, e.g., to make archive
with all the files required to run all (telemetry-based and binary)
performance tests.
