This header is semi-private, being used only in files related to
raw parsing, so move to the backend directory where those files
live. This allows removal of Makefile rules that symlink gram.h to
src/include/parser, since gramparse.h can now include gram.h from
within the same directory. This has the side-effect of no longer
installing gram.h and gramparse.h, but there doesn't seem to be a
good reason to continue doing so.
Per suggestion from Andres Freund and Peter Eisentraut

For the benefit of CI, which started running these header check scripts
in its CompilerWarnings task in commit 81b9f23c9c8, they should report
failure if any individual header failed to compile.

<sys/resource.h> is in SUSv2 and is on all targeted Unix systems. We
have a replacement for getrusage() on Windows, so let's just move its
declarations into src/include/port/win32/sys/resource.h so that we can
use a standard-looking #include. Also remove an obsolete reference to
CLK_TCK. Also rename src/port/getrusage.c to win32getrusage.c,
following the convention for Windows-only fallback code.

This CPU architecture has been discontinued. We already removed HP-UX
support, we never supported Windows/Itanium, and the open source
operating systems that a vintage hardware owner might hope to run have
all either ended Itanium support or never fully released support (NetBSD
may eventually). The extra code we carry for this rare ISA is now
untested. It seems like a good time to remove it.

HP-UX hardware is no longer produced, build farm coverage recently
ended, and there are no known active maintainers targeting this OS.
Since there is a major rewrite of the build system in the pipeline for
PostgreSQL 16, and that requires development, testing and maintainance
for each OS and tool chain, it seems like a good time to drop support
for:
* HP-UX, the operating system.
* HP aCC, the HP-UX native compiler.

Oversight in commit e2f0f8ed. Also add this file to the exclusion lists
in headerscheck and cpluscpluscheck, because Unix systems don't have a
header it includes.

headerscheck and cpluspluscheck should skip the recently-added
cmdtaglist.h header, since (like kwlist.h and some other similarly-
designed headers) it's not meant to be included standalone.
evtcache.h was missing an #include to support its usage of Bitmapset.
typecmds.h was missing an #include to support its usage of ParseState.
The first two of these were evidently oversights in commit 2f9661311.
I didn't track down exactly which change broke typecmds.h, but it
must have been some rearrangement in one of its existing inclusions,
because it's referenced ParseState for quite a long time and there
were not complaints from these checking programs before.
src/include/common/unicode_combining_table.h is currently not meant to
be included standalone. Things could be refactored to allow it, but
that would be beyond the present purpose. So adding an exclusion here
seems best.

We already had "cpluspluscheck", which served the dual purposes of
verifying that headers compile standalone and that they compile as C++.
However, C++ compilers don't have the exact same set of error conditions
as C compilers, so this doesn't really prove that a header will compile
standalone as C.
Hence, add a second script that's largely similar but runs the C
compiler not C++.
Also add a bit more documentation than the none-at-all we had before.
