Introduce the concept of "target query" and "resolved target". A target query is what the user specifies, with some things left to default. A resolved target has the default things discovered and populated. In the future, std.zig.CrossTarget will be rename to std.Target.Query. Introduces `std.Build.resolveTargetQuery` to get from one to the other. The concept of `main_mod_path` is gone, no longer supported. You have to put the root source file at the module root now. * remove deprecated API * update build.zig for the breaking API changes in this branch * move std.Build.Step.Compile.BuildId to std.zig.BuildId * add more options to std.Build.ExecutableOptions, std.Build.ObjectOptions, std.Build.SharedLibraryOptions, std.Build.StaticLibraryOptions, and std.Build.TestOptions. * remove `std.Build.constructCMacro`. There is no use for this API. * deprecate `std.Build.Step.Compile.defineCMacro`. Instead, `std.Build.Module.addCMacro` is provided. - remove `std.Build.Step.Compile.defineCMacroRaw`. * deprecate `std.Build.Step.Compile.linkFrameworkNeeded` - use `std.Build.Module.linkFramework` * deprecate `std.Build.Step.Compile.linkFrameworkWeak` - use `std.Build.Module.linkFramework` * move more logic into `std.Build.Module` * allow `target` and `optimize` to be `null` when creating a Module. Along with other fields, those unspecified options will be inherited from parent `Module` when inserted into an import table. * the `target` field of `addExecutable` is now required. pass `b.host` to get the host target.
