std.debug: prefer FP unwinding on targets where it is ideal
...
If the ABI requires a backchain pointer, FP unwinding is always possible, safe,
and fast, so there's really no reason not to use it.

drop support for powerpc64 ELF v1
...
* ELF v1 on powerpc64 is only barely kept on life support in a couple of Linux
distros. I don't anticipate that this will last much longer.
* Most of the Linux world has moved to powerpc64le which requires ELF v2.
* Some Linux distros have even started supporting powerpc64 with ELF v2.
* The BSD world has long since moved to ELF v2.
* We have no actual linking support for ELF v1.
* ELF v1 had confused DWARF register mappings which is becoming a problem in
our DWARF code in std.debug.
It's clear that ELF v1 is on its way out, and we never fully supported it
anyway. So let's not waste any time or energy on it going forward.

std.zig.system: add OS checks for QEMU in getExternalExecutor()
...
FreeBSD doesn't support the same number of platforms as Linux, and even then,
only has usermode emulation for a subset of its supported platforms.
NetBSD's usermode emulation support is apparently just broken at the moment.

feat: Reintroduce depth

Some decision-making might depend on the level of the traversal, so
it makes sense to expose depth here since it's stable, and not in the
automatic walker where it's not.

std.c: Also make Sigaction flags a c_uint for serenity

This matches all other platforms. Even if this field is defined as 'int'
in the C definition, the expectation is that the full 32-bit unsigned
integer range can be used. In particular this Sigaction initializer in
the new std.debug code was causing a build failure:
```zig
.flags = (posix.SA.SIGINFO | posix.SA.RESTART | posix.SA.RESETHAND)
