scripts/dump-target-info.pl: add new function to DUMP devices 

Add new function to dump-targer-info.pl to DUMP devices provided a
matching target/subtarget.

Example:

./scripts/dump-targer-info.pl devices ipq806x/generic

will produce the sorted list of devices defined in the following format:

device_id device_name

Devices may have alternative names, the script will dump each
alternative name in the same line of device_id.

Following the pattern:

device_id "PRIMARY DEVICE NAME" "ALT0 DEVICE NAME" "ALT1 DEVICE NAME" ...

Example:

tplink_ad7200 "TP-Link AD7200 v1/v2" "TP-Link Talon AD7200 v1/v2"

# DUMP duplicate info for each alternative device name and

# primary device name
# Alternative device titles always have the full list of
# all the alternative device name.
# The device name pattern for an alternative device name is
# Target-Profile-Name: ALT_NAME (PRIMARY_NAME)
# We compare the detected device name and check if it does
# match the alternative device name pattern with one of
# the alternative device name in Alternative device titles:
