output/ipv6: Add per-output configuration option to compress IPv6 IP addresses

[jlucovsky]

Continuation of #14871

Display IPv6 addresses in expanded (default) or compressed form per RFC-5952, based on the per-output configuration setting. Each of these outputs will display compressed IPv6 addresses when the per-output config setting ipv6-compress is yes.

• EVE output
• Fast output
• Alert-debug output
• Alert syslog output
• tcp-data log output

Here's an example of an IPv6 address with its compressed value::

fe80:0000:0000:0000:020c:29ff:faf2:ab42
fe80::20c:29ff:faf2:ab42

Link to ticket: https://redmine.openinfosecfoundation.org/issues/7399

Describe changes:

• Document configuration settings affecting IPv6 address display
• Default settings in suricata.yaml.in
• Utility function that generates compressed IPv6 addresses per RFC-5952
• EVE modifications to honor config setting
• Alert-debug/fast/syslog modifications to honor config setting.

Updates:

• Formatting fixup
• s-v: added missing suricata.yaml config file for tests where shortened IPv6 addrs are expected.
• Modified tcp-data log to use shorten config
• Combined certain commits (see output/ipv6: Add per-output configuration option to shorten IPv6 IP addresses #14819)
• Rust suggestions incorporated for utility function (see output/ipv6: Add per-output configuration option to shorten IPv6 IP addresses #14819)
• Rebased suricata and suricata-verify branches
• Reworded "shorten" to "compress", "long" to "expanded"

Provide values to any of the below to override the defaults.

• To use a Suricata-Verify or Suricata-Update pull request,
  link to the pull request in the respective _BRANCH variable.
• Leave unused overrides blank or remove.
