scripts: get_feat.pl: use its implementation for list-arch.sh
Add support for the same output format as the bash script, and use its implementation instead of the previous one. I opted to do such patch in order to have a single script responsible for parsing Documentation/features and produce different outputs. As someone may rely on the past format, which is easy to parse it, get_feat.pl now gains a new command with the same output format as the previous script. As a side effect, the perl script is a lot faster, as it reads each file only once, instead of parsing files several times via a for command and grep commands inside it. This patch also changes the features list order to be case-insensitive, in order to better match the output of the existing script.
