Tidy up claimed supported CPUs and OSes.

Browse Source 
* Remove arbitrary mention of certain endianness and bitness variants;
   it's enough to say that applicable variants are expected to work.
 * List RISC-V (known to work, being tested).
 * List SuperH and M88K (code exists, unknown status, like M68K).
 * De-list VAX and remove code (known not to work).
 * Remove stray trace of Alpha (support was removed years ago).
 * List illumos, DragonFlyBSD (known to work, being tested).
 * No need to single Windows out by listing a specific version, when we
   don't do that for other OSes; it's enough to say that we support
   current versions of the listed OSes (when 16 ships, that'll be
   Windows 10+).

In general, <productname>PostgreSQL</productname> can be expected to work on
these CPU architectures: x86, x86_64, PowerPC,
PowerPC 64, S/390, S/390x, Sparc, Sparc 64, ARM, MIPS, MIPSEL,
and PA-RISC. Code support exists for M68K, M32R, and VAX, but these
these CPU architectures: x86, PowerPC, S/390, Sparc, ARM, MIPS, RISC-V,
and PA-RISC, including
big-endian, little-endian, 32-bit, and 64-bit variants where applicable.
Code support exists for M68K, M88K, M32R, and SuperH, but these
architectures are not known to have been tested recently. It is often
possible to build on an unsupported CPU type by configuring with
<option>--disable-spinlocks</option>, but performance will be poor.

<productname>PostgreSQL</productname> can be expected to work on these operating
systems: Linux (all recent distributions), Windows (10 and later),
FreeBSD, OpenBSD, NetBSD, macOS, AIX, and Solaris.
<productname>PostgreSQL</productname> can be expected to work on current
versions of these operating systems: Linux, Windows,
FreeBSD, OpenBSD, NetBSD, DragonFlyBSD, macOS, AIX, Solaris, and illumos.
Other Unix-like systems may also work but are not currently
being tested. In most cases, all CPU architectures supported by
a given operating system will work. Look in
