This Change Adds initial Support for LongFiles in the VM,

They are:
1. Wrappers for OS APIs which  take or return PATHS

2. Fixing the usage of following Api's:

GetEnvironmentVariableW
SearchPathW
GetShortPathNameW
GetLongPathNameW
GetModuleFileName

Work remaining:
Remove fixed size buffers in the VM
