Merge pull request #14498 from ziglang/zig-build-api

Several enhancements to the build system. Many breaking changes to the API.

 * combine `std.build` and `std.build.Builder` into `std.Build`
 * eliminate `setTarget` and `setBuildMode`; use an options struct for `b.addExecutable` and friends
 * implement passing options to dependency packages. closes #14285
 * rename `LibExeObjStep` to `CompileStep`
 * move src.type.CType to std lib, use it from std.Build, this helps with populating config.h files.
