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

Update llvm-cheri to a new LLVM 17 based snapshot, llvm-cheriot to an
LLVM 18 based snapshot, and llvm-morello to a snapshot with new function
pointer semantics to better support compartmentalization.

Update the wrapper script to enable the new function pointer semantics
on sufficently new CheriBSD system.

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.

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

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
