Support long paths in CoreCLR runtime on Windows
The CoreCLR runtime is updated to support long file paths on Windows.
Pending updates to mscorlib.dll, the following scenarios are supported:
* Run managed apps from a long path.
* Load CoreCLR runtime and framework from a long path.
* Load user assemblies from a long path.
* Run CrossGen from a long path, with its input/output from a long path.
* Generate debug log file at a long path.
The following scenarios are not yet supported, and will be fixed in
future commits:
* Mscorlib.dll and framework assemblies are not yet long path compatible.
Note that until mscorlib.dll is fixed, most of the runtime changes can't
actually be used.
* Support on non-Windows platforms.
* Support for debugging and error reporting.
* Tools such as ilasm or ildasm.
