Feature/include refactor (#675)

* Refactor of path handling.
* Added PathInfo
* Changed ISlangFileSystem - such that has separate concepts of reading a file, getting a relative path and getting a canonical path
* Added support for getting a canonical path for windows/linux
* Made maps/testing around canonicalPaths
* User output remains around 'foundPath' - which is the same as before

* Small improvements around PathInfo
* Added a type and make constructors to make clear the different 'path' uses
* Fixed bug in findViewRecursively

* Checking and reporting for ignored #pragma once.

* Removed SLANG_PATH_TYPE_NONE as doesn't serve any useful purpose.

* Improve comments in slang.h aroung ISlangFileSystem

* Remove the need for <windows.h> in slang-io.cpp

* Ran premake5.

* Improvements and fixes around PathInfo.

* Fix typo on linix GetCanonical

* Make the ISlangFileSystem the same as before, and ISlangFileSystem contain the new methods.
Internally it always uses the ISlangFileSystemExt, and will wrap a ISlangFileSystem with WrapFileSystem, if it is determined (via queryInterface) that it doesn't implement the full interface.
