[Support] fix mingw-w64 build

ilya-biryukov · ilya-biryukov · commit 3e54404c7156 · 2019-11-06T15:18:58.000+01:00
Older versions of Mingw-w64 do not define _beginthreadex_proc_type, so we replace it with `unsigned (__stdcall *ThreadFunc)(void *)`. Fixes clangd/clangd#188 Patch by lh123! Differential Revision: https://reviews.llvm.org/D69879
