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.

sim: common: split up acinclude.m4 into individual m4 files This file is quite large and is getting unmanageable. Split it apart to follow aclocal best practices by putting one-macro-per-file. There shouldn't be any real functional changes here as can be seen in the configure script regens.

sim: smp: plumb igen flag down to all users While mips has respected sim_igen_smp at configure time (which was always empty since it defaulted smp to off), no other igen port did. Move this to a makefile variable and plumb it through the common IGEN_RUN variable instead so everyone gets it by default. We also clean up some redundant -N0 setting with multirun mips.
