[optimization_guide] Add locale filtering to `models_to_execute`

This CL adds locale filtering capability to the Finch feature parameter
`models_to_execute_v2`, and also adds a unit test.

It still supports the old `models_to_execute` parameter too.

The filtering works as below:

The parameter value delimits models by commas, and per-model locale
restrictions by colon. For example:

  FOO_MODEL:en:es-ES,BAR_MODEL,BAZ_MODEL:zh-TW

 - FOO_MODEL is restricted to English language users from any locale,
   and Spanish language users from the Spain es-ES locale.
 - BAR_MODEL is unrestricted by locale, and any user may load it.
 - BAZ_MODEL is restricted to zh-TW only, so zh-CN users won't load it.
