Add a Lua build-system (#28854)

Browse Source 
Reworking lua to allow easier substitution of the base lua implementation.

Also adding in a maintained version of luajit and re-factoring the entire stack 
to use a custom build-system to centralize functionality like environment 
variable management and luarocks installation.

The `lua-lang` virtual is now versioned so that a package that requires 
Lua 5.1 semantics can get any lua, but one that requires 5.2 will only 
get upstream lua.

The luaposix package requires lua-bit32, but only when built with a 
lua conforming to version 5.1.  This adds the package, and the 
dependencies, but exposed a problem with luarocks dependency 
detection.  Since we're  installing each package in its own "tree" and 
there's no environment  variable to list extra trees, spack now 
generates a luarocks config  file that lists all the trees of all the 
dependencies, and references  it by setting `LUAROCKS_CONFIG` 
in the build environment of every LuaPackage.  This allows luarocks 
to find the spack installed  dependencies correctly rather than 
trying (and failing) to download them.
