Add integrity check to validate installation

[rkusa]

To help debug issues caused by incomplete installations / updates, this PR adds an integrity check to the Lua files. It works as follows:

• Automatically embed hashes for all Lua files on build-time
• Validate existence and hash of all Lua files on runtime (when server is started)
• Additionally, compare version number of Lua files and DLL and make sure both match.

Example error:

2023-02-23 18:48:21.166 ERROR   SCRIPTING (Main): Mission script error: [string "M:\Development\DCS-gRPC\rust-server\lua\DCS-gRPC\grpc.lua"]:12: integrity check failed (hash mismatch of `M:\Development\DCS-gRPC\rust-server\lua\DCS-gRPC\grpc.lua`), DCS-gRPC is not started, please check your installation
