Ensure consistency of capitalization in RelativeDateTimeFormatter
Contains refactoring. Benchmarks below to show no appreciable
negative performance impact to formatters. We do now cache a new
type of formatter.
Benchmarks measured in microseconds on mako.
Before:
DateIntervalFormat_formatDateRange_DATE 244
DateIntervalFormat_formatDateRange_DATE_TIME 256
DateIntervalFormat_formatDateRange_TIME 208
RelativeDateTimeFormatter_getRelativeDateTimeString 207.2
RelativeDateTimeFormatter_getRelativeDateTimeString_ABBREV 218.2
RelativeDateTimeFormatter_getRelativeTimeSpanString 70.5
RelativeDateTimeFormatter_getRelativeTimeSpanString_ABBREV 67.4
After:
DateIntervalFormat_formatDateRange_DATE 237
DateIntervalFormat_formatDateRange_DATE_TIME 241
DateIntervalFormat_formatDateRange_TIME 200
RelativeDateTimeFormatter_getRelativeDateTimeString 149.4
RelativeDateTimeFormatter_getRelativeDateTimeString_ABBREV 161.8
RelativeDateTimeFormatter_getRelativeTimeSpanString 71.7
RelativeDateTimeFormatter_getRelativeTimeSpanString_ABBREV 69.0

Use ICU4J more in DateIntervalFormat and RelativeDateTimeFormatter
General strategy: Switch to ICU classes for Calendar, and generally
use ICU classes earlier to avoid multiple creations.
This also incorporates some feedback from narayan@ from
https://android-review.googlesource.com/#/c/145662/
Some small optimizations applied but the goal was not to make it
much faster, just to confirm it wasn't much slower. It has sped up
some methods, and slowed down others, but not much difference in
absolute terms.
All times in microseconds measured on a mako.
Original:
RelativeDateTimeFormatter_getRelativeDateTimeString 582.4
RelativeDateTimeFormatter_getRelativeDateTimeString_ABBREV 603.2
RelativeDateTimeFormatter_getRelativeTimeSpanString 39.9

After:
RelativeDateTimeFormatter_getRelativeDateTimeString 207.2
RelativeDateTimeFormatter_getRelativeDateTimeString_ABBREV 218.2
RelativeDateTimeFormatter_getRelativeTimeSpanString 70.5
RelativeDateTimeFormatter_getRelativeTimeSpanString_ABBREV 67.4
Original:
DateIntervalFormat_formatDateRange_DATE 290

icu4c DateIntervalFormat objects are expensive enough that we need to cache them.
It takes ~1ms to create a DateIntervalFormat on a z620, and around 8ms on a
current mobile device (Nexus 4). Add a small cache of recently-used formatters,
using a big lock rather than per-thread caches since this typically only
happens on the UI thread anyway, and because all the other frameworks date/time
formatting is behind a single lock too.
