vgpu in-guest producer in-tree, release CI, flexible vmie discovery

- src/si/vgpu-stream: in-guest vgpu producer built as a Windows cross-compiled target (if(WIN32)) - .gitea: release workflow — cross-build the agent and build/publish the deb against system vmie - cmake/makefile: resolve vmie from a source tree (LIBVMIE_PATH) or installed libvmie-dev

+ * C mirror of NvFBC's ToSys interface. The vendor header
+ * third_party/NvFBC/nvFBCToSys.h declares INvFBCToSys_v3 as a C++ abstract
+ * class (vtable of 5 pure-virtual
+ * __stdcall methods). We do NOT edit the vendor header; instead we replicate its
+ * single-inheritance vtable ABI as a COM-in-C interface so the producer stays
+ * pure C. Slot order MUST match declaration order in nvFBCToSys.h:
+ *   0 NvFBCToSysSetUp
+ *   1 NvFBCToSysGrabFrame
+ *   2 NvFBCToSysCursorCapture
+ *   3 NvFBCToSysGPUBasedCPUSleep
+ *   4 NvFBCToSysRelease
+ * On x64 (mingw/MSVC) `this` is the implicit first integer argument; __stdcall
+ * is a no-op for x64 so a plain pointer arg matches the vtable slot.
