Previously, we were splitting command line arguments on Windows using the same rules as on Unix, which was incorrect, most importantly because backslashes in the first component of a Windows command line invocation are not escaping anything but interpreted verbatim.

Updated the PR to be purely additive in a way that is guaranteed to only affect Windows. |

Explanation: This change implemented Windows-specific command line argument splitting for compilation database fields; previously, the Windows path separator was being interpreted as an escape character.
Scope: Without this change, sourcekit-lsp does not work with compilation databases on Windows. This change refactors command line argument splitting logic into Unix and Windows variants (the Windows variant being new code), with the callsite selecting between them via
#if os(Windows).Issue: Windows path separators in
compile_commands.jsonnot parsed correctly #1020Risk: Low; the change only affects Windows. As sourcekit-lsp was not working with compilation database on Windows before this change, there is no possible regression on this platform.
Testing: I have built and tested the 5.10 toolchain on Windows with this cherry-pick. CI will build and test for other platforms.
