Subject: [PATCH] perf(ext/fetch): improve decompression throughput by
 upgrading `tower_http` (#25806)

This commit improves the throughput when a Deno process is running as a proxy
server that deals with compressed data from the upstream server.

We have seen a performance degradation since v1.45.3 when we run a HTTP server
with Deno with a particular setting, where it fetches _compressed_ data from the
upstream server and forwards it to the end client. After some investigation, it
turned out that [tower_http::decompression] causes this issue, which was fixed
by the new version of this crate, v0.6.1.

[tower_http::decompression]: https://docs.rs/tower-http/0.6.0/tower_http/decompression/index.html

Fixes #25798
