gdb: remove uses of VLA
Remove uses of VLAs, replace with gdb::byte_vector. There might be more
in files that I can't compile, but it's difficult to tell without
actually compiling on all platforms.
Many thanks to the Linaro pre-commit CI for helping find some problems
with an earlier iteration of this patch.
