75bee892be Add LLDB and swift-reflection-dump support for WebAssembly 
This patch adds parsing and extracting of the Swift reflection
metadata data segments from within the WebAssembly DATA section and
tests it using swift-reflection-dump. This is needed to allow LLDB to
acces Swift reflection metadata when attached to WebAssembly
processes.

9779c18da3 Rename startswith to starts_with 
LLVM is presumably moving towards `std::string_view` -
`StringRef::startswith` is deprecated on tip. `SmallString::startswith`
was just renamed there (maybe with some small deprecation inbetween, but
if so, we've missed it).

The `SmallString::startswith` references were moved to
`.str().starts_with()`, rather than adding the `starts_with` on
`stable/20230725` as we only had a few of them. Open to switching that
over if anyone feels strongly though.

ef8825bfe6 Migrate llvm::Optional to std::optional 
LLVM has removed llvm::Optional, move over to std::optional. Also
clang-format to fix up all the renamed #includes.
