Fix mscordac exports

[janvorli]

The mscordbi depends on the PAL in mscordac and so it requires that all functions it uses from coreclr PAL are exported by the libmscordac. This got broken recently by a change in a header consumed by the mscordbi that pulled in usage of two functions for UTF16 to UTF8 conversion into the mscordbi (#96099).

This issue prevents debuggers using libmscordbi to initiate debugging.

This change fixes it by exporting those two functions from libmscordac.

I believe this should have been fixed on #97055. Cc @hoyosjs@mikem8361

Hmm, I've not noticed that change, it seems to work fine. I'm closing this PR then.
