Following up on discussion yesterday regarding this split.
Note, I'm expecting #3341 to do IdentifierId -> NameId in SemIR. It
might be worth adding NameId creation directly to StringStore if you're
content with this setup though.
Building on #3311, change SemIR to use the SharedValueStore. Since this
removes hermeticity, raw output no longer prints ints, reals, and
strings. TokenizedBuffer accessors are modified to return IDs because
values are often passed through in semantics without needing to read
them.
I would've put SharedValueStores on Context, except for the
GetArrayBoundValue convenience method. I felt awkward removing that, so
it's on File, at least for now. That's then used by the formatter and
Lower too. The flipside of this is that TokenizedBuffer has a
SharedValueStores only for printing, so maybe that's similar enough to
what File is doing.
This doesn't start shifting other SemIR members to ValueStore, but that
seems like a next step.
This updates lexing to use the data. I'll do checking separately, just
to split changes.
Note the ValueStore structure is also set up such that SemIR::File can
use it for other fields.

This file group exists to allow a `genquery` rule and a Python test to
verify our non-test dependency graph. We don't actually need to build
the binaries in the file group as part of that. The `genquery` rule
seems to do the right thing -- building it directly doesn't cause the
binaries in the group to be built. But without a manual tag, the group
itself is part of `:all` and thus part of `//...` and part of the rules
that will be built even with PR #3106. A consequence is that any change
to the toolchain causes several other binaries to be built as well
because this file group is in the impacted set. Making it manual should
avoid all of this, and without breaking the actual use from `genquery`.
For example, before this change, in a fully cached build after a `bazel
clean`:
```
> bazel test //bazel/check_deps:all
INFO: Invocation ID: 2d83ebee-4c00-425d-be33-23f42b079614

```
After this change:
```
> bazel test //bazel/check_deps:al
INFO: Invocation ID: c94089e8-a420-4d3c-9902-134e6b55b297

```
While here, re-generate the file group, and fix several issues it
uncovers: mark test utilities as `testonly` and update our LLVM package
allowlist to include `clangd`'s package.
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.

The main motivation for this is to get python loads in using the
`native-py` lint fix. However, enabling that made me wonder, maybe we
should fix in general?
`native-cc` is delayed, but not wholly cancelled (and `native-py`
picking up might indicate `native-cc` won't be too far behind). There's
also some automated fixes for `.append` and dict sorting -- this felt
okay to me, maybe not something to eagerly add but probably not worth
stopping buildifier from fixing (I've noticed the warnings in the past
and had been ignoring them).
Running everything does mean that load orders are sorted automatically
now, which I think is a positive. Most generally, I think these fixes
aren't _harmful_, and having them done automatically seems beneficial:
my biggest concern about `native-py` and `native-cc` was actually that
regressions wouldn't be caught, but this addresses that issue
automatically.
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.
