build(zig): keep all symbols for native Lua modules #41361

Native Lua modules loaded with `require` or `package.loadlib` resolve Lua
C API symbols from the nvim executable itself. Those symbols must stay in
the binary even when nothing inside nvim references them.

`rdynamic` is enough on Linux. On macOS the linker dead-strips
unreferenced symbols before rdynamic exports them, so `_lua_tothread` is
missing from the executable and loading such a module fails with:

    symbol not found in flat namespace '_lua_tothread'

Disable section garbage collection so all non-static symbols are kept.
