Primary motivation is documentation, but it will also hopefully simplify the code.
Also,
* Lower case the default output format names; this is in line with the custom ones (map keys) and how
it's treated all the places. This avoids doing `stringds.EqualFold` everywhere.
Closes#10896Closes#10620
* Add file context to minifier errors when publishing
* Misc fixes (see issues)
* Allow custom server error template in layouts/server/error.html
To get to this, this commit also cleans up and simplifies the code surrounding errors and files. This also removes the usage of `github.com/pkg/errors`, mostly because of https://github.com/pkg/errors/issues/223 -- but also because most of this is now built-in to Go.

During Hugo deploy when a remote MD5 is invalid (e.g due to multipart eTag) Hugo reads the entire remote file and calculates the MD5 again which can be slow.
This commit updates the file upload so that it will also store an MD5 hash in the cloud provider's attributes. e.g in AWS this looks like x-amz-meta-md5chksum: 26fe392386a8123bf8956a16e08cb841.
So we can use it and output.Format as map key etc.
This commit also fixes the media.Type implementation so it does not need to mutate itself to handle different suffixes for the same MIME type, e.g. jpg vs. jpeg.
This means that there are no Suffix or FullSuffix on media.Type anymore.

Currently, if cache invalidation is enabled when running `hugo deploy --dryRun` with , the deployer does not take the dry run flag into consideration and triggers CloudFront/GoogleCloudCDN cache invalidation if any of those services are configured.
This change will instead print a feedback message if a dry run is in effect and quiet mode is not enabled.
Fixes#7884
