Subject : [system-health] Run all SH stories in memory benchmarks
Author  : petrcermak
Commit description:
  
This patch modifies SH memory benchmarks (system_health.memory_desktop
and system_health.memory_mobile) to run all SH stories:

  - load:*   (already running)
  - browse:* (NEW)

As a result, all SH stories will also run in the SH smoke test on the
Chromium CQ
(benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.*).

*** NOTE TO SHERIFF ***
This patch is very likely to cause failures in the System Health
benchmarks (perf waterfall) and smoke tests (regular CQ). Please contact
me before reverting.
