This updates SourceBuffer to diagnostics. Some additional edits to
diagnostics were necessary due to issues moving arguments around, which
seems to stem from a compile error with clang 14 (fixed in later
versions).

Rearranges driver logic into CompilationUnits in order to associate
artifacts from the various stages of compilation.
Note, I'm not totally sure what the right thing to do is for
lower/codegen, so I'm just doing a rote change there for now that
mirrors prior phases (this is all the code supports anyways, so is
probably right for now regardless).
SourceBuffer error output is moved local for consistency with other
steps, and so that it's less ambiguous whether the error should be
expected to already include a filename.
Continuing with #3070. Just a dir and file rename (only prefix change is
lexer_file_test). Everything in the lex dir should be marked as a move.
Note, I think this closes#3070. There may still be further cleanup
later, but the organizational changes suggested there are being
completed.

Continuing with #3070. Just a dir and file rename (mostly removing
prefixes, although for parse_tree_fuzzer and parse_tree_file_test I'm
dropping "tree" instead of "parse"). Everything in the parse dir should
be marked as a move.
Continuing with #3070, this creates a `Lex` namespace for lexer. This is
probably the last namespace addition right now, and will be followed by
file moves, although I'll also share a PR separately moving member
classes out of TokenizedBuffer.
Continuing on #3070.
I moved ParseTree::Node to just Parse::Node, versus Parse::Tree::Node.
Other name changes are just removing "Parse" or "Parser" prefixes.
In EnumBase, I'm directly defining operator<< because the ostream.h
approach just isn't working, not for either of Parse::State nor
Parse::NodeKind. Errors look like:
```toolchain/parser/parser_context.cpp:449:34: error: invalid operands to binary expression ('llvm::raw_ostream' and 'const Carbon::Parse::State')
output << "\t" << i << ".\t" << entry.state;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~
```
The expected template in `Carbon::` is not in the error list; I only see
the:
```
./common/ostream.h:112:6: note: candidate template ignored: requirement 'std::is_base_of_v<std::ostream, llvm::raw_ostream>' was not satisfied [with S = llvm::raw_ostream, T = Carbon::Parse::State]
auto operator<<(S& standard_out, const T& value) -> S& {
^
```
I'm still prodding at this, but not seeing an obvious fix.

Add a language server for carbon as part of GSoC.
This currently does code outline using toolchain parser.
See development steps in utils/vscode/README.md for running and using
language server.
