Add feature flag to turn off %self (#10262)
This is the last remnant of the old percent expansion.

It has the downsides of it, in that it is annoying to combine with
anything:

```fish
echo %self/foo
```

prints "%self/foo", not fish's pid.

We have introduced $fish_pid in 3.0, which is much easier to use -
just like a variable, because it is one.

If you need backwards-compatibility for < 3.0, you can use the
following shim:

```fish
set -q fish_pid
or set -g fish_pid %self
```

So we introduce a feature-flag called "remove-percent-self" to turn it
off.

"%self" will simply not be special, e.g. `echo %self` will print
"%self".
