Eager autoload ActiveSupport::ExecutionContext

Browse Source 
ExecutionContext was added as a regular autoload when it was introduced
in 6bad959. However, the class is not currently referenced anywhere on
the boot path. This means that the file will currently be required
during the first request/job/query (currently its loaded when the to_run
callback defined in active_support.reset_execution_context is executed).

To maximize CoW and ensure that the first request/job/query doesn't have
any extra latency, ExecutionContext should be eager autoloaded instead.
