PCI(e) host controllers behave in different ways (some more buggy than
others) in what value they use to indicate that an endpoint is not
present. In most cases the VID/DID is all ones (PCIE_ID_NONE) but in
others it's all zeroes, and some may even have the VID all zeroes and
the DID all ones, or vice-versa.
Add a macro to easily test for all these possibilities. The "all ones"
and "all zeroes" cases have been verified to exist on actual HW
supported by Zephyr, however the test for the mixed cases is simply
based on what Linux considers valid values (drivers/pci/probe.c in the
Linux kernel tree).

Use SHELL_CMD_ARG() for argument check and add help, looking like:
...
$ pcie -h
pcie - PCI(e) device information
Subcommands:
ls :List PCIE devices
Usage: ls [bus:device:function] [dump]

Add argument dump for dumping first 16 PCI configuration space
registers same way lspci -x is doing. Also parse bdf string as
argument. pcie can be called following way:
uart:~$ pcie 0:1f.4
...
uart:~$ pcie 0:1f.4 dump
...

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

These have been redefined in various places - better to have them in a
single place that different users can use.

With this refactoring of pcie directory, RC drivers are placed under
host/ directory, EP drivers are placed under endpoint/ directory and
they are completely independent of each other.
