Update to Wine 5.15. This includes the following changes:
- Initial implementation of the XACT Engine libraries.
- Beginnings of a math library in MSVCRT based on Musl.
- Still more restructuration of the console support.
- Direct Input performance improvements.
- Exception handling fixes on x86-64.
- Various bug fixes.
lib/wine/libx3daudio1_7.def "disappeared" from the Staging patchset,
without migrating to the default case. That's in addition to a number
of the usual dose of packaging changes.
