devel/llvm-{cheri,cheriot,morello}: update

Update to the latest snapshots.

We've done OK so far with installing standard headers as part of
devel/llvm## ports so extend that to these ports.  This is certainly
correct for llvm-cheriot.  Practical testing is likely required for the
others.

devel/llvm-morello: new snapshot

Includes:

[Morello] Disable tail call stack arg area reuse for bounded memargs

devel/llvm-{cheri,cheriot,morello}: link llvm-cxx{dump,filt}

These commands were some how not linked into bin long ago.  Correct
this error.

(Some other commands are also missing, but were specifically missing
llvm-cxxfilt).

devel/llvm-{cheri,cheriot,morello}: assorted fixups

Allow override of GH_PROJECT and GH_ACCOUNT[0] and fix GH_PROJECT in
llvm-cheriot.  No change in the source, but the filename is now
corrected.

Centralize include of Makefile.snapshot.

devel/llvm-{cheri,cheriot,morello}: new snapshots

Major changes:
    llvm-cheri: merge LLVM 15
    llvm-cheriot: switch the fork at github.com/CHERIoT-Platform
    llvm-morello: merge LLVM 14

Rework patching and filtering of commands and man pages to better
accomdate version skew between the different ports now that all three
have different bases.

Centralize the addition of ${.CURDIR}/files to EXTRA_PATCHS.

bsd.sites.mk: Update all ports using USE_GITLAB

Replace GL_COMMIT by GL_TAGNAME in all ports. The new GL_TAGNAME is
backwards-compatible (accepting any commit hash as before), but also
understands an actual tag name. Moving to tag names where appropriate is
left to individual ports' maintainers.

devel/llvm-{cheri,morello}: add a STATIC_LIBS option

When enabled assorted LLVM componant static libraries are included in
the package.  Unlike mainstream LLVM ports I've disabled this by

llvm-cheri:
 - This updates from an LLVM 13 base to an LLVM 14 base.
 - Save a little compile time by dropping MIPS support.  The CHERI
   MIPS target still exists, but CheriBSD no longer supports it and the
   places that use it (e.g., https://cheri-compiler-explorer.cl.cam.ac.uk)
   use a Linux build.

llvm-morello:
 - Minor optimization improvements

As with regular llvm ports, don't install std*.h as they conflict with
FreeBSD versions.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

llvm-{cheri,morello}: Update to new shapshots
