Sets recommended max Xmx 32G when set_recommended_max_xmx experiment is enabled

[arvindram03]

We set the Xmx to the recommended max value(32G) with set_recommended_max_xmx is enabled. Under 32G JVM enables CompressedOops. CompressedOops utilizes memory more efficiently, and has positive impact on GC performance and cache hit rate.

It'll be flexible if we allow passing the xmx value via the experiment.
eg: --experiments=set_recommended_xmx=<xmx bytes>

We do not want to expose the plug too much with this change as well. Which later becomes hard to control. In future, might be a generic way to control all the jvm args which will be covering this as well.
