Adds a tool `swift-symbolgraph-extract` that reads an existing Swift module and prints a platform- and language-agnostic JSON description of the module, primarly for documentation. Adds a small sub-library `SymbolGraphGen` which houses the core implementation for collecting relevant information about declarations. The main entry point is integrated directly into the driver as a mode: the tool is meant to be run outside of the normal edit-compile-run/test workflow to avoid impacting build times. Along with common options for other tools, unique options include `pretty-print` for debugging, and a `minimum-access-level` options for including internal documentation. A symbol graph is a directed graph where the nodes are symbols in a module and the edges are relationships between them. For example, a `struct S` may have a member `var x`. The graph would have two nodes for `S` and `x`, and one "member-of" relationship edge. Other relationship kinds include "inherits-from" or "conforms to". The data format for a symbol graph is still under development and may change without notice until a specificiation and versioning scheme is published. Various aspects about a symbol are recorded in the nodes, such as availability, documentation comments, or data needed for printing the shapes of declarations without having to understand specifics about the langauge. Implicit and public-underscored stdlib declarations are not included by default. rdar://problem/55346798
