Pass 1. We first go thru all search paths and try to open it using CWin32ReadOnlyFile. In most cases the file can be opened using it, so we can skip CStdioFile in this pass which should be a good speedup. Pass 2. We failed to open it using CWin32ReadOnlyFile, now were going thru everything again but this time were going to use CStdioFile. If it now fails, the file doesn't exist.

This optimizes the file seach by splitting the CWin32ReadOnlyFile and CStdioFile into seperate passes.
when it searches for a file, it tries to open the file in every single searchpath and trying both(when in
rb) seems pointless.in most cases CWin32ReadOnlyFile should return the valid handle for
rbsearches.This should be ~50% speed up for files that aren't in the first search path like
platform_misc_000.vpkNote
Since I currently can't build the master branch I couldn't check and test it in the lastest version but it should work.
