std: Remove a handful of things deprecated during the 0.15 release cycle

- std.Build.Step.Compile.root_module mutators -> std.Build.Module
- std.Build.Step.Compile.want_lto -> std.Build.Step.Compile.lto
- std.Build.Step.ConfigHeader.getOutput -> std.Build.Step.ConfigHeader.getOutputFile
- std.Build.Step.Run.max_stdio_size -> std.Build.Step.Run.stdio_limit
- std.enums.nameCast -> @field(E, tag_name) / @field(E, @TagName(tag))
- std.Io.tty.detectConfig -> std.Io.tty.Config.detect
- std.mem.trimLeft -> std.mem.trimStart
- std.mem.trimRight -> std.mem.trimEnd
- std.meta.intToEnum -> std.enums.fromInt
- std.meta.TagPayload -> @FieldType(U, @TagName(tag))
- std.meta.TagPayloadByName -> @FieldType(U, tag_name)
