cmdline-opts: category cleanup

Option cleanups:

 --get is not upload
 --form* are post
 - added several options into ldap, smtp, imap and pop3
 - shortened the category descriptions in the list

category curl fixes:

 --create-dirs removed from 'curl'
 --ftp-create-dirs removed from 'curl'
 --netrc moved to 'auth' from 'curl'
 --netrc-file moved to 'auth' from 'curl'
 --netrc-optional moved to 'auth' from 'curl'
 --no-buffer moved to 'output' from 'curl'
 --no-clobber removed from 'curl'
 --output removed from 'curl'
 --output-dir removed from 'curl'
 --remove-on-error removed from 'curl'

Add a "global" category:

- Made all "global" options set this category

Add a "deprecated" category:

- Moved the deprecated options to it (maybe they should not be in any
 category long term)

Add a 'timeout' category

- Put a number of appropriate options in it

Add an 'ldap' category

- Put the LDAP related option in there

Remove categories "ECH" and "ipfs"

- They should not be categories. Had only one single option each.

Remove category "misc"

- It should not be a category as it is impossible to know when to browse
  it.

--use-ascii moved to ftp and output
--xattr moved to output
--service-name moved to auth

Managen fixes:

- errors if an option is given a category name that is not already setup
  for in code

- verifies that options set `scope: global` also is put in category
  `global´

Closes #14101
