### 📚 Description

Trac branch `u/gh-collares/gap-gc` from sagemath#34701, now migrated to GitHub.
Currently based atop sagemath#35093; will rebase once that is merged.

The rest of the description below is copied from sagemath#34701:

A refactor in sagemath#27946 introduced "unprotected" (not surrounded by
`GAP_Enter`/`GAP_Leave`) `GAP_ValueGlobalVariable` calls. I believe this
might be a GC hazard, because after updating to GAP 4.12.1 I started
seeing aarch64 crashes on NixOS infrastructure such as:

```
#0  0x0000fffff79740e8 in wait4 ()
#1  0x0000fffff5dc6b78 in print_enhanced_backtrace ()
#2  0x0000fffff5dc8190 in sigdie ()
#3  0x0000fffff5dcb1c0 in cysigs_signal_handler ()
#4  0x0000fffff7ffb7cc in __kernel_rt_sigreturn ()
#5  0x0000ffff99a0bf28 in ConvString ()
#6  0x0000000000000000 in ?? ()
#7  0x0000000000000000 in ?? ()
#8  0x0000000000000000 in ?? ()
#9  0x0000ffff99989930 in Pr ()
#10 0x0000ffff9998aa18 in CloseOutput ()
#11 0x0000ffff99884828 in capture_stdout () at /build/sage-
src-9.7/pkgs/sagemath-standard/sage/libs/gap/element.pyx:154
...
```
I also see cases where `capture_stdout` throws errors such as
`sage.libs.gap.util.GAPError: Error, Length: <list> must be a list (not
the integer 255)` and then crashes. Both types of errors are fixed by
this ticket.

Note that I am nesting `GAP_Enter`/`GAP_Leave` calls because I didn't
remove the preexisting calls inside `capture_stdout`. That's because I
feared removing the innermost calls might create a new footgun (and I
believe nested `GAP_Enter`/`GAP_Leave` calls are explicitly supported),
but removing them should cause no problem. Removing them might even be
preferable for performance reasons, I don't know.

Fixes sagemath#34701
