fs: fix realpath inode link caching

The `fs.realpath` / `fs.realpathSync` cache already seen symbolic links
using the inode number which may be longer that max supported
JS number (2**53) and will therefore be incorrectly handled by possibly
entering infinite loop of calling stat on the same node.

This PR changes those functions (where appropriate) to use
bigint for inode numbers.

Fixes: nodejs#33936
