fix(build): check that LuaJIT has required modules for compilation (#16714)

Browse Source 
Apparently some installations of LuaJIT do not have the "jit.bcsave"
module which is required for pre-compilation. Check that this module
exists before using LuaJIT as luac and if it doesn't, skip compiling
bytecode.
