formatMeasure

Formats value with its unit for display: the number follows the OS locale, the symbol does not.

ICU's MeasureFormat would also translate the symbol and pick the locale's own spacing, and an earlier revision of this used it. It cannot be reached from here: this function is called from commonTest, which runs against the Android target's stub android.jar where every android.icu call throws, and commonTest cannot switch to Robolectric because it also compiles for iOS. Symbols were fixed English before this function existed, so nothing regressed — only the translation improvement was given up.

NaN and infinity render as the shared placeholder, because telemetry floats use NaN as an in-band "absent" marker.
