Sam Lantinga 3c9510f2ce Fix msvc analyzer warnings 
- Initialize some out variables that are annotated inout in the function setting them.

- Fix 'dwVerHandle' might not be '0' warning from msvc analyzer calling GetFileVersionInfoA. MSDN says that
  the lpdwHandle param to GetFileVersionInfoSize is optional (set to zero) and the dwHandle param to
  GetFileVersionInfoA is ignored. msvc goes a step further and explicitly warns if dwHandle is not provably 0.

Fixes the following:
SDL3\src\stdlib\SDL_string.c(2359): warning C6054: String 'text' might not be zero-terminated.
SDL3\src\video\windows\SDL_windowsevents.c(897): warning C6001: Using uninitialized memory 'devName'.
SDL3\src\video\windows\SDL_windowskeyboard.c(644): warning C6388: 'dwVerHandle' might not be '0':  this does not adhere to the specification for the function 'GetFileVersionInfoA'.
