FEATURE: Site setting for blocking onebox of URLs that redirect (#16881)
Meta topic: https://meta.discourse.org/t/prevent-to-linkify-when-there-is-a-redirect/226964/2?u=osama.

This commit adds a new site setting `block_onebox_on_redirect` (default off) for blocking oneboxes (full and inline) of URLs that redirect. Note that an initial http → https redirect is still allowed if the redirect location is identical to the source (minus the scheme of course). For example, if a user includes a link to `http://example.com/page` and the link resolves to `https://example.com/page`, then the link will onebox (assuming it can be oneboxed) even if the setting is enabled. The reason for this is a user may type out a URL (i.e. the URL is short and memorizable) with http and since a lot of sites support TLS with http traffic automatically redirected to https, so we should still allow the URL to onebox.

Only block domains at the final destination (#15689)
In an earlier PR, we decided that we only want to block a domain if 
the blocked domain in the SiteSetting is the final destination (/t/59305). That 
PR used `FinalDestination#get`. `resolve` however is used several places
 but blocks domains along the redirect chain when certain options are provided.

This commit changes the default options for `resolve` to not do that. Existing
users of `FinalDestination#resolve` are
- `Oneboxer#external_onebox`
- our onebox helper `fetch_html_doc`, which is used in amazon, standard embed 
and youtube
  - these folks already go through `Oneboxer#external_onebox` which already
  blocks correctly

FIX: Respect blocked domains list when redirecting (#15656)
Our previous implementation used a simple `blocked_domain_array.include?(hostname)`
so some values were not matching. Additionally, in some configurations like ours, we'd used
"cat.*.dog.com" with the assumption we'd support globbing.

This change implicitly allows globbing by blocking "http://a.b.com" if "b.com" is a blocked 
domain but does not actively do anything for "*".

An upcoming change might include frontend validation for values that can be inserted.

Régis Hanol 7109d94ee7 FIX: properly invalidate inline oneboxes when rebaking
When rebaking a post we were invalidating _regular_ oneboxes but not inline oneboxes.

DEV: also renamed 'InlineOneboxer.purge' to 'InlineOneboxer.invalidate' to keep
the API consistent with 'Oneboxer.invalidate'

Sam Saffron 0fb497eb23 DEV: use Discourse.cache over Rails.cache
Discourse.cache is a more consistent method to use and offers clean fallback
if you are skipping redis

This is part of a larger change that both optimizes Discoruse.cache and omits
use of setex on $redis in favor of consistently using discourse cache

Bench does reveal that use of Rails.cache and Discourse.cache is 1.25x slower
than redis.setex / get so a re-implementation will follow prior to porting

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

Guo Xiang Tan 142571bba0 Remove use of `rescue nil`.
* `rescue nil` is a really bad pattern to use in our code base.
  We should rescue errors that we expect the code to throw and
  not rescue everything because we're unsure of what errors the
  code would throw. This would reduce the amount of pain we face
  when debugging why something isn't working as expexted. I've
  been bitten countless of times by errors being swallowed as a
  result during debugging sessions.
