feat(debug): update print_memory_map.py

Browse source 
Add some entries in blx_symbols, that are used when the flag
SEPARATE_CODE_AND_RODATA is not enabled (__RO_* and __TEXT_RESIDENT_*).
Add all new symbols that were not yet present in the script.
Correct __BSS_END to __BSS_END__, and add __BSS_START__.
Add new *_XLAT_TABLE_* symbols.
As those strings are longer than 22, update display format string to
be dependent on the longest string.
The script also skips lines for which the _START__ and _END__
symbols have the same address (empty sections).
