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.
