review Thai collation: alternate=shifted

Description

Do we really need to set alternate=shifted for Thai? This was done for where Åke Persson is quoted as saying that the Thai punctuation should really use a quaternary level. I just documented quaternary relations in LDML, and ICU 53 should support them (with at most 3 quaternary differences from some base).

In general, it would be best if no language used alternate=shifted by default. I just answered a question from a user who was surprised that ASCII punctuation was ignored with the Thai collator.

Åke is also quoted with "BTW, the UCA 4.1.0 tried unsuccessfully to correct the default Thai collation in the DUCET. James Clark proposed corrections in UTC:L2/06-084, but that was not accepted for some reason, and the issue was handed over to be solved by CLDR."

I remember that this caused some problems for IBM in Thailand when we tried to do otherwise, so need to make sure we coordinate with them on that, as well as Ake.
