nxgdb/mm: warning if corrupted memory node found
...
If the nodesize is 0, we cannot iterate to next node, siliently return None will cause memleak command to generate false positive report with no warnings.
Add log to indicate such case.

pynuttx: optimize memory leak check by skipping previously checked pointers
...
Reduce leak analysis time from 12s to 7.8s, achieving a 35% performance improvement that tested on an internal project.
1. Use memoryview to avoid creating int objects, reducing overhead
2. Store checked pointers in a dictionary for efficient lookups, improving performance.
3. While dictionary operations have some cost, the overall speedup is significant.

nxgdb/fs: simplify inode print and add more options
...
Use Inode.__repr__ for print and use single line for all information.
Add 'verbose' and 'nodetype' option to show more details and only print specifiy node type like PIPE.
Add / to name for pseudodir.
Catch memory error when accessing node element.
E.g.
(gdb) foreach inode --nodetype pipe
