[idd] debug: full Unicode handling and log as UTF-8

Browse Source 
This commit makes `CDebug` use Unicode internally instead of whatever
random code page is in use. It also gets rid of the horrible character
counting and replaces that with `vasprintf` and `vaswprintf` helpers
(partially inspired by Linux) which allocates a buffer.

For HRESULT logging, the error code in both hex and decimal are included.

The output is now guaranteed to be UTF-8.
