Cleanup experiment code

[niranjan-uma-shankar]

Proposed Changes

• I noticed that the signup page still fires the experiment assignment API for calypso_signup_onboarding_deemphasize_free_plan. Since this experiment is no longer active, we can remove the code.

Legend

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.
