Fix Wear ProtoLayout and WatchFace date/time formatting for SDK 37

Targeting SDK 37 introduces updated ICU localization data and changes
Robolectric's Choreographer/Looper scheduling behavior, meaning we need
to update the follwoing:

1. Wear Complications Date/Time Formatting:
   - SDK 37 ICU uses Narrow No-Break Space (\u202f)
     in day-period markers (e.g. Spanish "a. m."). Sanitizing \u202f
     ensures shortened 12-hour strings stay within the strict 7-character complication limit.
   - 12-hour short-text time formatting bypassed the locale override table for the "hmm" skeleton, causing locales like Bulgarian ("bg") to
     exceed character bounds. Unifying skeleton lookups across both date
     and time formatters ensures locale-specific overrides are respected.

2. ProtoLayout Dynamic Date Formatting:
   - DynamicDateFormat previously assumed day-period ("a") patterns were
     always single-character, ignoring skeleton length. Preserving the
     pattern length allows multi-character/narrow day-period formats
     (such as "aaaaa") to evaluate correctly across all locales.

3. ProtoLayout Inflation Animation Test Timing:
   - In SDK 37, Robolectric shifts Choreographer to a software-based
     no-VSYNC model where frame callbacks are posted directly as Looper
     messages. Draining all delayed tasks via runToEndOfTasks() prematurely
     advanced the clock through the entire animation duration, discharging
     animation completion and releasing quota permits early. Advancing
     virtual time specifically to the 600ms transition delay allows the
     in-flight animation to hold its quota permit during the overlapping
     transition test.
