Nodes: Add "Legacy" to legacy node UI names, skip in search

Currently there is no way to tell that these node types are deprecated
in the UI. This commit adds "(Legacy)" to the end of the names.
It also makes it simple to skip these in the various node searches
more automatically than before.

Fixes T101700
