gh-98030: socket: add missing TCP socket options

[matttbe]

A few TCP socket options have been added to the Linux kernel these last few years.

This commit adds all the ones available in Linux 6.0:

https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91

While at it, the TCP_FASTOPEN option has been moved lower in the list just to keep the same order as in tcp.h to ease future synchronisations.

Please note that I initially wanted to get socket.TCP_FASTOPEN_CONNECT. I was going to add only this one but while at it, here are all the missing ones.

Hi @gpshead,

Thank you for the review! I'm sorry for the delay, I missed the notification when I was on holiday.

I just listed all new constants in the doc as requested. Feel free to tell me if it is not what you had in mind!

Note: switching to 'cce836296016463032495c6ca739ab469ed13d3c'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at cce8362960 gh-98030: socket: add missing TCP socket options (#98031)
