Add missing copyright dates to scripts and sources

To find any files with a missing copyright declaration, use the following script:

# ========================
#!/bin/sh

# Find files with copyright declarations, and list their file extensions
exts=$(grep -Ril --exclude-dir .git --exclude-dir 3rdparty\
                 --exclude-dir programs/fuzz 'Copyright.*Arm' | sed '
  s/.*\///
  s/.*\./*./
  s/.*/-name "&"/
' | sort -u | sed -n '
  :l
    N
    $!bl
  s/\n/ -o /gp
')

# Find files with file extensions that ususally include copyright extensions,
# but don't include a copyright declaration themselves.
eval "find\
  '(' -path './.git' -o -path './3rdparty' -o -path './programs/fuzz' ')' -prune\
  -o ! -path './tests/data_files/format_pkcs12.fmt'\
     ! -path './programs/psa/psa_constant_names_generated.c'\
     '(' $exts ')' -print" | xargs grep -Li 'Copyright.*Arm'
