Since some variables with module LatinIME are defined but not used,
when compiled with build combination "sdk_pc_x86_64-userdebug" and
build command "mmm packages/inputmethods/LatinIME", the following
code lines will be reported that "variable 'XXX' set but not used".
(should be similar for all the other build combinations)

Repeated 10 times for each:
terminal_position_lookup_table.cpp:74:9 removedEntryCount
terminal_position_lookup_table.cpp:85:9 removedEntryCount
proximity_info_state_utils.cpp:493:9 tempTime
trie_map.cpp:56:9 unusedRegionSize
suggestion_results.cpp:100:9 index

Repeated 80+ times:
proximity_info_utils.h:75:25 proximityChar

With this patch we are removing some of the unused variables and
putting the C++ 17 attribute [[maybe_unused]] to the others which
are used for logging. Then all the related build warnings have been
eliminated.

Test: mmm packages/inputmethods/LatinIME, presubmit check.

This will ensure that the target stays green.
Note: we will clean up the explicit unit_tests:true once cc_test default is changed.

This CL addresses compiler warnings when building libjni_latinime.so
with NDK from Android Studio.

There should be no behavior change.

Host-side C++ test in LatinIME is no longer actively used and is
actually not compatible with Android Studio build.

Let's just remove this for now.
