Reland "refactor(fetch): reimplement fetch with hyper instead of reqwest" (#24593)

Originally landed in
https://github.com/denoland/deno/commit/f6fd6619e708a515831f707438368d81b0c9aa56.
Reverted in https://github.com/denoland/deno/pull/24574.

This reland contains a fix that sends "Accept: */*" header for calls made
from "FileFetcher". Absence of this header made downloading source code
from JSR broken. This is tested by ensuring this header is present in the
test server that servers JSR packages.
