RFR (S) 8232168: Fix non wide char canonicalization on Windows

[David Holmes]

Hi Ralf,

This isn't a hotspot issue but a core-libs one.

The use of a hotspot-runtime test seems more opportunistic than anything 
else - is it just for code coverage? I would expect to find a more 
appropriate test somewhere in core-libs.

Thanks,
David

This change always calls the wcanonicalize() method, since the old implementation doesn't work for all path lengths <= MAX_PATH. In addition the canonicalizeWithPrefix() method has been removed, since it seems to be not used anymore.
