emulators/virtualbox-ose{,-kmod,-nox11}-70: Add new ports VirtualBox 7.0.24

General status:
* VirtualBox 7.1.x is still not fully ported to FreeBSD, so we are
  adding 7.0.x in experimental/test mode.
* 7.0.x is being tested on hosts of several FreeBSD developers and
  users.
* As far as we know, 7.0.x has the same system requirements as 6.1.x -
  amd64 with VT-x (we even tested it on Core 2 Duo E6xxx), so after
  confirming stability with more users, 7.0.x is expected to replace
  6.1.x.
* The following ports also need to be created for this replacement:
  - emulators/virtualbox-ose-additions-70;
  - emulators/virtualbox-ose-additions-nox11-70;
  - www/phpvirtualbox-70.
* If 7.1.x has the same system requirements, then when we port 7.1.x,
  it will replace 7.0.x.

This patch is a joint effort by several FreeBSD developers and users.
Thanks to everyone involved!
