[Support] Convert BinaryStream class zoo to 64-bit offsets

Most PDB fields on disk are 32-bit but describe the file in terms of MSF
blocks, which are 4 kiB by default.

So PDB files can be a bit larger than 4 GiB, and much larger if you create them
with a block size > 4 kiB.

This is a first (necessary, but by far not not sufficient) step towards
supporting such PDB files. Now we don't truncate in-memory file offsets (which
are in terms of bytes, not in terms of blocks).

No effective behavior change. lld-link will still error out if it were to
produce PDBs > 4 GiB.

Make llvm::StringRef to std::string conversions explicit.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

[LLVMDebugInfoPDB] - Use cantFail() instead of assert().

Currently injected-sources-native.test fails with "Expected<T>
value was in success state.
(Note: Expected<T> values in success mode must still be checked
prior to being destroyed)"
when llvm is compiled with LLVM_ENABLE_ABI_BREAKING_CHECKS in Release.

The problem is that getStringForID returns Expected<StringRef>
and Expected value must always be checked, even if it is in success state.
Checking with assert only helps in Debug and is wrong.

llvm-pdbdump: Fix several smaller issues with injected source compression handling

- getCompression() used to return a PDB_SourceCompression even though
the docs for IDiaInjectedSource are explicit about the return value
being compiler-dependent. Return an uint32_t instead, and make the
printing code handle unknown values better by printing "Unknown" and
the int value instead of not printing any compression.

- Print compressed contents as hex dump, not as string.

- Add compression type "DotNet", which is used (at least) by csc.exe,
the C# compiler. Also add a lengthy comment describing the stream
contents (derived from looking at the raw hex contents long enough
to see the GUIDs, which led me to the roslyn and mono implementations
for handling this).

- The native injected source dumper was dumping the contents of the
whole data stream -- but csc.exe writes a stream that's padded with
zero bytes to the next 512 boundary, and the dia api doesn't display
those padding bytes. So make NativeInjectedSource::getCode() do the
same thing.
