Function:
- INIT_FindEXEPath

Abstract:
- Determine the full, canonical path of the current executable by searching
- $PATH.
+ Check whether the executable path is valid, and convert its type (LPCSTR -> LPWSTR)
Parameters:
- LPCSTR exe_name : file to search for
+ LPCSTR exe_name : full path of the current executable
Return:
pointer to buffer containing the full path. This buffer must be released
