Add CtsIcu4cTestCases for ICU4C API coverage

- cintltest and intltest are the executable binaries
  running the devices.
- cintltest and intltest are basically compiled against
  libicuuc and libicui18n, except if the APIs are available
  in the NDK surface in libicu, the test will link that in favour
  of NDK. So the APIs provided in the NDK will have the API coverge,
  while the test can keep using the hidden APIs in libicuuc, and
  libicui18n.
  cts_headers/ are the same as libicuuc and libicui18n headers, except
  that unicode/urename.h is modified by the generate_ndk.py to select
  the NDK API surface.

Bug: 160350521
Test: atest CtsIcu4cTestCases
Test: Inspect the symbol table manually by "objdump -TC cintltst"
