fix: stream and compress reporter output

[hi-ogawa]

Description

Resolves #9216

This PR replaces flatted with turbo-stream for blob and html reporter output file format. This avoids generating a large string before writing out to a file.

// previously
import { stringify } from "flatted"
const outpuString = stringify(data);

// this PR
import { encode } from "turbo-stream"
const outputStream = encode(data)
   .pipeThrough(new TextEncoderStream())
   .pipeThrough(new CompressionStream('gzip'))

(ACTUALLY, it turned out RangeError: Invalid string length still occurs because it joins the chunks before flushing jacob-ebey/turbo-stream#77)

TODO

• streaming output
  • gzip
• optimize structure (this might not be effective since gzip compresses similar strings better)
• flag to opt-out importDurations collection (in a separate PR)
• test
  • https://github.com/hi-ogawa/vitest-9216-repro
