perf(ivy): don't store public input names in two places (#33798)

Before this change a public name of a directive's input
was stored in 2 places:
- as a key of an object on TNode.index;
- as a value of PropertyAliasValue at the index 1

This PR changes the data structure so the public name is stored
only once as a key on TNode.index. This saves one array entry
for each and every directive input.

PR Close #33798
