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`.

Replace `catch bun.outOfMemory()`, which can accidentally catch
non-OOM-related errors, with either `bun.handleOom` or a manual `catch
|err| switch (err)`.

## Summary
Fixes a prerequisite issue in #21792 where `Bun.serve()` incorrectly
rejected TLS arrays with exactly 1 object.
The original issue reports a WebSocket crash with multiple TLS configs,
but users first encounter this validation bug that prevents
single-element TLS arrays from working at all.
## Root Cause
The bug was in `ServerConfig.zig:918` where the condition checked for
exactly 1 element and threw an error:
```zig
if (value_iter.len == 1) {
return global.throwInvalidArguments("tls option expects at least 1 tls object", .{});
}
```
This prevented users from using the syntax: `tls: [{ cert, key,
serverName }]`
## Fix
Updated the validation logic to:
- Empty TLS arrays are ignored (treated as no TLS)
- Single-element TLS arrays work correctly for SNI
- Multi-element TLS arrays continue to work as before
```zig
if (value_iter.len == 0) {
// Empty TLS array means no TLS - this is valid
} else {
// Process the TLS configs...
}
```
## Testing
- ✅ All existing SSL tests still pass (16/16)
- ✅ New comprehensive regression test with 7 test cases
- ✅ Tests cover empty arrays, single configs, multiple configs, and
error cases
## Note
This fix addresses the validation issue that prevents users from
reaching the deeper WebSocket SNI crash mentioned in #21792. The crash
itself may require additional investigation, but this fix resolves the
immediate blocker that users encounter first.
