refactor: mark `--verbose` as deprecated

[Wwwsylvia]

What this PR does / why we need it:

1. Mark the --verbose flag as deprecated and print verbose output by default for the following six commands. As a result, the --verbose flag will be hidden in the help doc, and there will be a warning message when --verbose is specified.

   • oras push
   • oras pull
   • oras attach
   • oras cp
   • oras manifest push
   • oras blob push

2. Add the corresponding E2E tests

The deprecation of --verbose for oras discover will be addressed with #1534.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged): Fixes #1533 Prerequisite: #1553

Examples: oras pull BEFORE:

oras pull AFTER:

oras pull --verbose BEFORE:

oras pull --verbose AFTER:

oras pull --verbose=false BEFORE:

oras pull --verbose=false AFTER:

oras pull --help BEFORE:

oras pull --help AFTER:

Maybe mark it deprecated in the Printer object too

Currently it is still functioning, we can consider removing the whole verbose stuff in v1.4.0 or something? From my understanding, the printer will be refactored by @wangxiaoxuan273 soon as part of handler refactoring.
