refactor(ext): align error messages (#25496)

Browse source 
Aligns the error messages in the ext/http and a few messages in the
ext/fetch folder to be in-line with the Deno style guide.

This change-set also removes some unnecessary checks in the 00_serve.ts.
These options were recently removed, so it doesn't make sense to check
for them anymore.
