[clangd] [C++20] [Modules] Add modules suffix for 'Header' Source Switch (#131591)
Support the trivial "header"/source switch for module interfaces.

I initially thought the naming are bad and we should rename it. But
later I feel it is better to split patches as much as possible.

From the codes it looks like there are problems. e.g., `isHeaderFile`.
But let's try to fix them in different patches.

f71ffd3b73 [clang-tools-extra] Use std::optional instead of llvm::Optional (NFC)
This patch replaces (llvm::|)Optional< with std::optional<.  I'll post
a separate patch to clean up the "using" declarations, #include
"llvm/ADT/Optional.h", etc.

This is part of an effort to migrate from llvm::Optional to
std::optional:

71f557355d [clang-tools-extra] Add #include <optional> (NFC)
This patch adds #include <optional> to those files containing
llvm::Optional<...> or Optional<...>.

I'll post a separate patch to actually replace llvm::Optional with
std::optional.

43fbbcbfa9 [clangd] llvm::Optional::value => operator*/operator->
std::optional::value() has undesired exception checking semantics and is
unavailable in some older Xcode. The call sites block std::optional migration.

76fcfea283 [clang-tools-extra] Don't including None.h (NFC)
These source files no longer use None, so they do not need to include
None.h.

649ef3386b [clang-tools-extra] Use std::nullopt instead of llvm::None (NFC)
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

8edfc2f814 [clangd] Cleanup of readability-identifier-naming
Auto-generated patch based on clang-tidy readability-identifier-naming.
Only some manual cleanup for `extern "C"` declarations and a GTest change was required.

I'm not sure if this cleanup is actually very useful. It cleans up clang-tidy findings to the number of warnings from clang-tidy should be lower.  Since it was easy to do and required only little cleanup I thought I'd upload it for discussion.

One pattern that keeps recurring: Test **matchers** are also supposed to start with a lowercase letter as per LLVM convention. However GTest naming convention for matchers start with upper case. I would propose to keep stay consistent with the GTest convention there. However that would imply a lot of `//NOLINT` throughout these files.

To re-product this patch run:
```
run-clang-tidy -checks="-*,readability-identifier-naming" -fix -format ./clang-tools-extra/clangd
```

To convert the macro names, I was using this script with some manual cleanup afterwards:

6ef1ccecf7 [clangd] Rename DiagnosticsConsumer -> ClangdServer::Callbacks, and make it optional
Summary:
This reflects its current function better and avoids confusion with clang::DiagnosticConsumer.

The old name/constructor is left around temporarily for compatibility.
