Remove LocaleDataTest#testInitLocaleData_icu4cConsistency test

The new implementation in LocaleData is not consistent with the
old implementation depending on icu4c, as mentioned in the test
comment. Also, the test only tests a subset of fields and locales.
It proves the new behavior is different.

It's almost impossible to compile the test in the future because
ART module will be unbundled, and the test uses internal methods/fields
in both ART and ICU. So removing the test here.

The test was only used to catch the behavior change/bug fixes,
and make sure the new behavior more correct/expected than the
old implementation. Now the test and commment are removed, but
the comment can be found in the commit message in
https://r.android.com/1250330.
