* Fixed all includes of OpenEXR in the engine and plugins
* Will allow building other middlewares that rely on OpenEXR without hassle (ex: OpenVDB)
* Created build scripts (Windows only for now)
* Replicated a few UE specific changes that were made under Deploy/OpenEXR-2.3.0 to the source, so that a rebuild of the lib will not erase them

Added a NET_CORE define to allow us to have changes side by side.
The AWS S3 changes are required due to us requiring to upgrade the S3 assembly version to get net core support (which made all methods async).
The ACL checks for files are not available in the system libraries of net core, as such the api is a bit different.
AutomationToolLauncher now just spawns a subprocess when used in netcore, as netcore does not support custom AppDomains and shadow copying. We will generally need to revisit this for netcore as this whole feature of building the source for UAT in UAT is not really possible.
To enable this set environment variable "UE_USE_DOTNET=1", note that with netcore all applications change their output path so this will likely break a bit of tooling when enabled.

* Added support for more complex Msbuild conditions (using static property methods) as we use this to do per platform checks in the csprojs.
* Tweaks to the parsing of csprojs as expecations are different for netcore (mostly for how configurations are defined)
* Lastly if -dotnetcore flag is present when generating projects, use the netcore project files instead.

This because we do not need this added dependency and it is not available by default in net core.

While these were present no csproj actually referenced them and built them, thus these files do not actually compile.

[CL 14518566 by Andrew Davidson in ue5-main branch]
- Changed plugin module descriptor internals to allow for an empty platform whitelist (which means no platforms are enabled), in the case of all platforms in the whitelist are not around
- Added some dummy DDPI.ini files for "fake platforms" to the Engine so that the above directory checks will not strip out the shared platform directories from projects
