Support latest Zig version after build phase separation

[Techatrix]

The Zig build system has been reworked internally in #35428. It's been separated into a "make" process and a "configure" process. ZLS can be updated once the build system protocol has been implemented.

Here is what users can do until this issue has been resolved:

• use Zig 0.17.0-dev.387+31f157d80 with master branch ZLS
• use Zig 0.16.0 with ZLS 0.16.0
• use latest master branch of Zig without ZLS (ZLS may still work partially just without any zig build support)
