[PATCH 0/7] MR5082: winebuild: Preparation for ARM64X support

[Jacek Caban (＠jacek)]

Right now we filter entry points for the target architecture when parsing .spec file. On ARM64X, we're interested in entry points for two different targets. On MSVC (and experimental LLVM), creating importlibs that support both ARM64EC and ARM64 requires passing two .def files. With .spec files, we may generate them both from the same .spec file.

This separates per-target exports into a separate struct, while parser stores all entry points specified in the .spec file.
