bptato 67442471ae Fix broken poll and nfds_t bindings (#24331)
This fixes several cases of the Nim binding of nfds_t being inconsistent
with the target platform signedness and/or size.

Additionally, it fixes poll's third argument (timeout) being set to Nim
"int" when it should have been "cint".

The former is the same issue that #23045 had attempted to fix, but
failed because it only considered Linux. (Also, it was only applied to
version 2.0, so the two branches now have incompatible versions of the
same bug.)

Notes:

* SVR4's original "unsigned long" definition is cloned by Linux and
Haiku. Nim got this right for Haiku and Linux-amd64, but it was wrong on
non-amd64 Linux.
* Zephyr does not have nfds_t, but simply uses (signed) "int". This was
already correctly reflected by Nim.
* OpenBSD poll.h uses "unsigned int", and other BSD derivatives follow
suit. This being the most commonly copied definition, the fallback case
now returns cuint. (This also seems to be correct for the OS X headers I
could find on the web.)
* This changes Nintendo Switch nfds_t to cuint from culong. It is
purportedly a FreeBSD derivative, so I *think* this is correct, but I
can't tell because I don't have access to the Nintendo Switch headers.

I have also moved the platform-specific Tnfds to posix.nim so that we
can reuse the fallback logic on all platforms. (e.g. specifying the size
in posix_linux_amd64 only to then use when defined(linux) in posix_other
seems redundant.)
