26b42416d4 UBT: Add a "hybrid" executor, which uses the XGE executor for large numbers of parallel actions, and the Parallel executor for any leaf actions that will not saturate the local machine. For platforms that take a long time to link, this frees up XGE to be used for compiling other branches. 
To enable, set <BuildConfiguration><bEnableHybridExecutor>true</bEnableHybridExecutor></BuildConfiguration> in the BuildConfiguration.xml file.

b4e5d0ee81 UBT: If UnrealHeaderTool needs rebuilding, do so from the same process rather than spawning a child UBT instance. This is significantly faster, since we're already fully initialized and have cached a lot of state.

c5b6fefcc7 UBT: Add a DirectoryItem class, similar to FileItem, which caches directory contents and properties. Allows constructing FileItem objects from enumerated FileInfo objects, avoiding additional I/O hit to determine attributes. DirectoryLookupCache is converted to use DirectoryItem objects as part of this change.

f01ddb51ae UBT: Add support for building multiple targets in parallel. 
* A makefile is now constructed for each target, and the outdated actions are combined into a single graph before execution.
* Makefiles are used in all build modes, regardless of whether they are saved to disk, and represent the vector by which a target's build actions are passed to the executor.
* The -JsonExport= argument has been removed, and a separate JsonExport mode has been added (invoke with eg. "-Mode=JsonExport UE4Editor Win64 Development")
* Multiple action history files are kept open at one time, and a hierarchy is used for each target.

0c9707d678 UBT: Use compiler-generated dependency information for source file dependencies. This ensures that the dependency list is accurate, and makes incremental builds more reliable. 
* A standalone Win32 application called cl-filter is used to parse output from running the Visual Studio compiler with the /showIncludes option, and generate a dependency list similar to Clang.
* Actions which produce an external dependency list declare it explicitly. If the dependency list is missing, or any of the contents are out of date, the action is rebuilt.
* The contents of dependency lists are cached by the CppDependencyCache class for future iterations.
