[clangd][clang] Crash in SignatureHelp on invalid decltype(__uuidof(...)) assertion in PPCaching.cpp:151

The crash is reproducibly triggered by `textDocument/signatureHelp` on the declaration line of the minimized repro,near the end of the parameter declarator.
Assertion:
```
CachedTokens[CachedLexPos-1].getLastLoc() == Tok.getAnnotationEndLoc() && "The annotation should be until the most recent cached token
```
```
initialize -> initialized -> didOpen -> textDocument/signatureHelp-> shutdown -> exit
```
source code
```cxx
template void test_uuidofExpr(decltype(__uuidof(T::member)) arg) {}
```

It crashes no matter whether `-fms-extensions` is enabled.
Maybe it's related to https://github.com/llvm/llvm-project/issues/165246, since its shares similar crash point and assertion, but the stacktrace is no the same.
```

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
