Check system locale when picking up an initial SpellChecker.
Since Ia25e7b4f308778891929e31b8cbd741f6848cce4, the TSMS has
picked up the first found spell checker no matter regardless of
the system locale.
The primary goal of this CL is to introduce a low-risk fix for
the situation where two or more spell checker services are
pre-installed but they are well different from each other in
terms of supported languages. Solving the problem in more
ambiguous and complicated situation is beyond the goal of
this CL.
With this CL, we still pick up the first found spell checker
but also require the spell checker supports a certain locale.
We will try several locales starting with the system locale
to some fallback locales until we find one appropriate spell
checker. If no spell checker is picked up in this process,
we simply pick up the first one as we have done.
Examples about what locales will be checked are:
A. System locale: en_US
1. en_US
2. en_GB
3. en
B. System locale: en
1. en
2. en_US
3. en_GB
C. System locale: en_IN
1. en_IN
2. en_US
3. en_GB
4. en
D. System locale: ja_JP
1. ja_JP
2. ja
3. en_US
4. en_GB
5. en
E. System locale: fil_PH
1. fil_PH
2. fil
3. en_US
4. en_GB
5. en
F. System locale: th_TH_TH
1. th_TH_TH
2. th_TH
