perf(ext/web): add op_encode_binary_string (#16352) 
Add a new op to use in `reader.readAsBinaryString(blob)`.

```
File API binary string: 400b    35.12 µs/iter    (21.93 µs … 3.27 ms)  31.87 µs 131.95 µs 217.63 µs
File API binary string: 4kb     46.49 µs/iter    (29.36 µs … 4.42 ms)   42.5 µs 122.48 µs  155.1 µs
File API binary string: 2.2mb    4.17 ms/iter     (1.75 ms … 8.54 ms)   5.48 ms   7.39 ms   8.54 ms
```

**main**

```
benchmark                          time (avg)             (min … max)       p75       p99      p995
--------------------------------------------------------------------- -----------------------------
File API binary string: 400b    56.17 µs/iter  (43.09 µs … 784.52 µs)   49.6 µs 177.18 µs 241.23 µs
File API binary string: 4kb     277.2 µs/iter   (240.29 µs … 1.84 ms) 269.87 µs 649.79 µs 774.46 µs
File API binary string: 2.2mb  180.03 ms/iter (173.32 ms … 194.35 ms) 182.54 ms 194.35 ms 194.35 ms
```

It can also handle bigger files, when encoding a 200mb file, main
crashes with OOM

deno web

Op crate that implements Event, TextEncoder, TextDecoder and File API (https://w3c.github.io/FileAPI).

Testing for text encoding is done via WPT in cli/.
