Add a new generator for JS → Zig bindings. The bulk of the conversion is done in C++, after which the data is transformed into an FFI-safe representation, passed to Zig, and then finally transformed into idiomatic Zig types. In its current form, the new bindings generator supports: * Signed and unsigned integers * Floats (plus a “finite” variant that disallows NaN and infinities) * Strings * ArrayBuffer (accepts ArrayBuffer, TypedArray, or DataView) * Blob * Optional types * Nullable types (allows null, whereas Optional only allows undefined) * Arrays * User-defined string enumerations * User-defined unions (fields can optionally be named to provide a better experience in Zig) * Null and undefined, for use in unions (can more efficiently represent optional/nullable unions than wrapping a union in an optional) * User-defined dictionaries (arbitrary key-value pairs; expects a JS object and parses it into a struct) * Default values for dictionary members * Alternative names for dictionary members (e.g., to support both `serverName` and `servername` without taking up twice the space) * Descriptive error messages * Automatic `fromJS` functions in Zig for dictionaries * Automatic `deinit` functions for the generated Zig types Although this bindings generator has many features not present in `bindgen.ts`, it does not yet implement all of `bindgen.ts`'s functionality, so for the time being, it has been named `bindgenv2`, and its configuration is specified in `.bindv2.ts` files. Once all `bindgen.ts`'s functionality has been incorporated, it will be renamed. This PR ports `SSLConfig` to use the new bindings generator; see `SSLConfig.bindv2.ts`. (For internal tracking: fixes STAB-1319, STAB-1322, STAB-1323, STAB-1324) --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Alistair Smith <hi@alistair.sh>
