Reland "[clang-doc] Refactoring mapper to map by scope"

Relanding with a minor change to prevent an assertion on release bots.

The result of this adjusted mapper pass is that all Function and Enum
infos are absorbed into the info of their enclosing scope (i.e. the class
or namespace in which they are defined). Namespace and Record infos are
passed along to the final output, but the second pass creates a reference
to each in its parent scope. As a result, the top-level final outputs are
Namespaces and Records.

[clang-doc] Implement reducer portion of the frontend framework

Implements a simple, in-memory reducer for the mapped output of the
initial tool. This creates a collection object for storing the
deduplicated infos on each declaration, and populates that from the
mapper output. The collection object is serialized to LLVM
bitstream. On reading each serialized output, it checks to see if a
merge is necessary and if so, merges the new info with the existing
info (prefering the existing one if conflicts exist).

[clang-doc] Setup clang-doc frontend framework

Setting up the mapper part of the frontend framework for a clang-doc
tool. It creates a series of relevant matchers for declarations, and
uses the ToolExecutor to traverse the AST and extract the matching
declarations and comments. The mapper serializes the extracted
information to individual records for reducing and eventually doc
generation.
