[libedit] Add new port

[TartanLlama]

• Changes comply with the maintainer guide.
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx.
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

A note on the license, as it may not be immediately obvious: the license for this package has three clauses, but I have marked it as using the four-clause University of California BSD license. I believe this is correct, as the SPDX entry for this license includes the following text: "Captures the retroactive deletion of the third (advertising) clause of the Original BSD license for BSD-licensed code developed by UC Berkeley and its contributor".

This addresses the second half of #1268

Perhaps we can refer to Debian package selecting "version": "3.1-20240808", but I am not sure whether 3.1 will be increased as expected in the future.

[TartanLlama]

This codebase is based on code that's part of the NetBSD project and the 3.1 part is with regards to NetBSD versioning, so it's not entirely relevant to users of this library. The last time the major version changed was 2009, and the comment in the changelog reads:

MAJOR.MINOR version is now 3.0.
This is due to NetBSD changing time_t and dev_t to 64 bits. It does
not really effect this package.

I think the date version is what is relevant to users, so is the best option

Sorry, is there anything to resolve here or is this comment just informational for others reading?

It is just for reference.
