TokenManager defines Token interfaces for the clang syntax-tree. This is the level
of abstraction that the syntax-tree should use to operate on Tokens.
It decouples the syntax-tree from a particular token implementation (TokenBuffer
previously). This enables us to use a different underlying token implementation
for the syntax Leaf node -- in clang pseudoparser, we want to produce a
syntax-tree with its own pseudo::Token rather than syntax::Token.

We should see `NodeRole` information in the dump because that exposes how the
accessors will behave.
Functional changes in the dump:
* Surround Leaf tokens with `'`
* Append `Node` dumps with `NodeRole` information, except for unknown roles
* Append marks to `Node` dumps, instead of prepending
Non-functional changes:
* `::dumpTokens(llvm::raw_ostream, ArrayRef<syntax::Token>, const
SourceManager &SM)` always received as parameter a `syntax::Token *`
pointing to `Leaf::token()`. Changed the function to
`dumpLeaf(llvm::raw_ostream, syntax::Leaf *, const SourceManager&)`
* `dumpTree` acted on a Node, rename to `dumpNode`

In this process we also create some other tests, in order to not lose
coverage when focusing on the annotated code
Differential Revision: https://reviews.llvm.org/D85962
We add the method `SyntaxTreeTest::treeDumpEqualOnAnnotations`, which
allows us to compare the treeDump of only annotated code. This will reduce a
lot of noise from our `BuildTreeTest` and make them short and easier to
read.
