perf: pre-compile embedded Lua source into bytecode (#16631)

The Lua modules that make up vim.lua are embedded as raw source files into the
nvim binary. These sources are loaded by the Lua runtime on startuptime. We can
pre-compile these sources into Lua bytecode before embedding them into the
binary, which minimizes the size of the binary and improves startuptime.
