Change `SortingConsumer` from sorting by last processed token
(per-phase) to
additionally allow diagnostics to request sorting by start position
(line and
column) when the last processed token is the same.

Mainly because "sorting_diagnostic_consumer" is legacy, since
`SortingDiagnosticConsumer` became `SortingConsumer`. Also better
reflecting contents of these files.
Where I'm not renaming, I'm less positive about dropping "diagnostics"
from "file_diagnostics" and "null_diagnostics" (which contain both a
consumer and emitter, and "null.h" seems like poor naming), so not doing
that here. Also "diagnostic.h" contains `struct Diagnostic`, so is a
decent fit.

Building on #4411, avoid using StringLiteral in format strings. This
includes a diagnostic check to prevent regressions (which is also how I
gathered issues).
Note, I haven't looked at `std::string` uses yet, but we might need
things like that to be able to pass strings in code back to the user.
StringLiteral though means that it's literally written down in the
toolchain, at which point it should probably be written in the format
string instead of separately.

Building on https://github.com/carbon-language/carbon-lang/pull/4411,
replace format_provider uses (other than `TokenKind`, which is more on
the okay side of things)
Also does some edits to `ClassMemberDefinition` to try to better match
diagnostic style
Instead of stringifying types in the caller in some cases, add new types
to represent:
- `InstIdAsType`: an `InstId` diagnostic argument that represents a type
expression that should be included in the diagnostic
- `InstIdAsTypeOfExpr`: an `InstId` diagnostic argument that represents
an expression whose type should be included in the diagnostic
For these cases, we can produce more user-friendly descriptions of a
type than we can with a canonicalized `TypeId`. Add comments to
discourage using `TypeId` diagnostic arguments when one of the above can
be used, and move over existing uses where it's straightforward to do
so.
Move type stringification code to its own files and out of `SemIR::File`
to make `File` smaller and to further discourage the direct use of the
stringification logic.
Also update type printing to include the `` ` `` delimiters surrounding
the type. The intent is that we will eventually want to include other
information when formatting a type, like Clang does when printing a
typedef (`'string' (aka 'std::basic_string<char>')`), and such
formatting requires that the diagnostic machinery produces the `` ` ``s
itself.
There are a couple of cases where we really want to format valid Carbon
type syntax directly into a diagnostic, rather than an `aka` or similar,
because the diagnostic text includes part of the type itself, for
example: ``"consider using `partial {0}`"``. For such cases, a `Raw`
form of the diagnostic argument types is added: `TypeIdAsRawType` and
`InstIdAsRawType`. In principle we could instead use ``"consider using
`partial {0:raw}`"``, but our diagnostic machinery isn't set up for
that.

This is a primarily automated change:
- Search & replace for capitalization
-
`(CARBON_DIAGNOSTIC\((?:\n\s+)?\w+,(?:\n\s+)?\s\w+,(?:\n\s+)?\s")([A-Z])`
- `$1\L$2`
- Search & replace for period
-
`(CARBON_DIAGNOSTIC\((?:\n\s+)?\w+,(?:\n\s+)?\s\w+,(?:\n\s+)?\s"(?:[^)]|\n)+)\.("[,)])`
- `$1$2`
- Limited search & replace for `ERROR: ` -> `error: ` in streamed things
- Leaving a TODO for command_line because there's more cleanup that can
be done there
- Modify diagnostic_consumer.cpp
- ERROR -> error
- WARNING -> warning

Part of this is also a plan to change "ERROR:" -> "error:" in
diagnostics. I think I'm the odd one out on sentence casing. The rest is
mostly trying to figure out advice that I think we can live with.
Note I'm not immediately planning to rewrite all diagnostics (unless
maybe there's a simple regex). I'm more trying to redirect style a
little to where preferences lie, particularly for new diagnostics.
