perf(fs): don't canonicalize path when opening file if --allow-all is passed (#28716)
Fixes #28702.

Super artificial benchmark:

```ts
const perf = performance;

async function asyncOpen() {
  const start = perf.now();
  for (let i = 0; i < 100_000; i++) {
    const file = await Deno.open("./foo.txt");
    file.close();
  }
  const end = perf.now();
  console.log(end - start);
}

function syncOpen() {
  const start = perf.now();
  for (let i = 0; i < 100_000; i++) {
    const file = Deno.openSync("./foo.txt");
    file.close();
  }
  const end = perf.now();
  console.log(end - start);
}

if (Deno.args[0]?.trim() === "async") {
  await asyncOpen();
} else {
  syncOpen();
}
```

Results (average of 10 for each):

```
deno sync               1785.59
deno-this-pr sync       491.69
deno async              1839.71
deno-this-pr async      528.78
```
