Include lldb-zig for nightlies

[bangbangsheshotmedown]

I wanted to debug my zig program, but i couldn't (see bellow)

I suggest shipping lldb-zig build in the nightly version of zig

https://github.com/jacobly0/llvm-project/tree/lldb-zig

Important: it must be built with scripting enabled LLDB_ENABLE_PYTHON (require swig), and should build lldb-server separatly, this is important to have good IDE debugging: https://github.com/vadimcn/codelldb/blob/master/MANUAL.md#alternate-lldb-backends

I can't seem to set break points with  `@breakpoint()`, it refuses to compile:

game-run
└─ run game failure
error: the following command terminated unexpectedly:
cd /home/ryuukk/dev/kdomz/bin && /home/ryuukk/dev/kdomz/zig-out/bin/game 
Build Summary: 10/12 steps succeeded; 1 failed
game-run transitive failure
└─ run game failure
error: the following build command failed with exit code 1:

and when i try to break with `lldb` i get: 

(lldb) breakpoint set --name main
Breakpoint 1: where = game`start.main + 71, address = 0x000000000116f094

   640         while (c_envp[env_count] != null) : (env_count += 1) {}
   641         const envp = @as([*][*:0]u8, @ptrCast(c_envp))[0..env_count];
   642     
warning: This version of LLDB has no plugin for the language "zig". Inspection of frame variables will be limited.

i copied the executable from `zig-out/bin` to `bin/` because i need some files in there

build: https://gist.github.com/ryuukk/99c206b6538f39eae7bb59a7a02a5c7b

ideas?
