`HeaderDependencies.cpp` cannot be compiled with
`SWIFT_INCLUDE_TOOLS=OFF` because it depends on `Config.h` which is only
generated while building tools. Exclude it from the build to fix `all`
target.
Follow-up to b39dba32f3
Changes to the headers imported by Swift files aren't not correctly
propagated in CMake/Ninja. So changes to C/C++ headers didn't rebuild
ASTGen modules. Move the similar hack from SwiftCompilerSources and use
it in ASTGen as well.

- Added a couple of new targets:
- libswiftDriver, which contains most of the driver implementation
- swift_driver, which produces the actual executable
- Added centralized version information into libswiftBasic.
- Added a new "Driver Design & Internals" document, which currently describes
the high-level design of the Swift driver.
- Implemented an early version of the functionality of the driver, including
versions of the Parse, Pipeline, Bind, Translate, and Execute driver stages.
Parse, Pipeline, and Bind are largely implemented; Translate and Execute are
early placeholders. (Translate produces "swift_driver --version" and "ld -v"
commands, while Execute performs all subtasks sequentially, rather than in
parallel.)
This is just the starting point for the Swift driver. Tests for the existing
behavior are forthcoming.
