Andrew Burgess 1d506c26d9 Update copyright year range in header of all files managed by GDB
This commit is the result of the following actions:

  - Running gdb/copyright.py to update all of the copyright headers to
    include 2024,

  - Manually updating a few files the copyright.py script told me to
    update, these files had copyright headers embedded within the
    file,

  - Regenerating gdbsupport/Makefile.in to refresh it's copyright
    date,

  - Using grep to find other files that still mentioned 2023.  If
    these files were updated last year from 2022 to 2023 then I've
    updated them this year to 2024.

I'm sure I've probably missed some dates.  Feel free to fix them up as
you spot them.

# This test is in the same vein as amd64-pseudo-unwind, making sure we can
# read write pseudo registers in outer frames. However, it tests a special
# case where the debug info includes unwind information for a pseudo register
# but not the underlying raw register. This can happen for the pseudo register
# s16, which is the bottom half of the raw register d8.
