Subject: Add rake dev:cache task to enable dev mode caching.

Taken from @Sonopa's commits on PR #19091.

Add support for dev caching via "rails s" flags.

Implement suggestions from @kaspth.

Remove temporary cache file if server does not have flags.

Break at 80 characters in railties/CHANGELOG.md

Remove ability to disable cache based on server options.

Add more comprehensive options: --dev-caching / --no-dev-caching
