Add a setting to load I18n translations when an API is compiled

I18n reads its locale files on the first lookup, so in an app that
precompiles its API the first error a process answered still paid for the
load: 3.65 ms against 0.87 ms once the translations were in memory.
Grape.config.eager_load_i18n makes compiling eager-load the I18n backend,
so an app calling compile! at boot pays it there.

It is off by default. Rails, where Grape is most often mounted, already
eager-loads I18n when config.eager_load is on, and keeps it lazy
otherwise; forcing it there would make every I18n.reload! load at once in
development, and could read the translations before the app's
initializers have set its load path.

The backend is asked directly, as one that does not inherit
I18n::Backend::Base may have no eager_load!.
