[Indic] Further adjust base algorithm for Sinhala
Apparently if there is C,V,ZWJ,C, the first C will be base, but if
it's C,ZWJ,V,C, the second one will be.
Note that Uniscribe implements this differently, by breaking syllable in
the case of C,ZWJ,V,C and putting the first consonant in one syllable
and the rest in the next syllable.
Sinhala failures down from 208 to 158 (0.0581209%). No changes to
Khmer.

One Devanagari test regressed, plus 10 Malayalam (at 1545 now).

[Indic] Improve Sinhala base algorithm and reph positioning
Sinhala does not have half forms. And most (all?) consonants can be
base, except when preceded by ZWJ, which would request a subjoined form.
Hence switch the base algorithm to categorize with Khmer, start search
at start, and stop at a ZWJ.
Also, mark all pos=base consonants after base to be subjoined. Mark
base itself to have pos=base.
Finally, adjust Sinhala's reph position to after-main.
Brings down Sinhala failures from 455 to 328 (0.120656%).

When removing zero-width marks, don't remove ligatures
If a mark ligated, it probably should NOT be removed.

If, say, a H,ZWJ,C ligature was formed, we don't want the code to detec
that as a Halant. So, ignore ligatures when matching category in

Seems to be about what Uniscribe does. Not exactly. But close enough.
More consonants will start a new cluster.
A few scripts went way down in failures. In particular:
- Devanagari failures went down from 490 to 56.
- Telugu went down from 113 to 49.
Other scripts went down slightly or didn't change. New numbers:
