7c9fc905a6 LazUtf8: In UTF8CompareStrCollated only call AnsiCompareStr is ACP_RTL is defined, since in all other cases 
AnsiCompareStr = widestringmanager.CompareStrAnsiStringProc = UTF8CompareStr.
If ACP_RTL is not defined call Utf8CompareStr, since this is now does proper collation and is faster than
converting to WideString.

77e5428b3f LazUtf8: firts attempt to rewrite Utf8CompareStr and Utf8CompareText so that it's results will be more consistent with 
AnsiCompareStr/WideCompareStr and AnsiCompareTex/WideCompareText.
(
The old implementation was in effect a copy of CompareStr and, this made the claim about proper collation in
Utf8CompareText (which uses Utf8CompareStr) rather ludicrous.
The new implementaion is slower, mainly becaus of the fact we cannot use CompareMemrange/CompareByte anymore,
and we have to iterate the bytes ourselves. This fact alone contributes much more to the loss in speed than
the fact we use WideCompareStr on the 2 differing codepoints:
- iterating in a for loop: adss a factor of appr. 10 to the time needed
- using the final WideCompareStr adds a factor of about 1.6 to the time meeded.
Because of the slowdown in speed in Utf8CompareStr, Utf8CompareText now calls WideCompareText directly, which is
now appr. the same speed as converting to lowercase and then calling Utf8CompareStr
)
