  [lldb] Avoid trie prefix recompuation (NFC) (#200026)

Avoid O(depth) string concatenations for every symbol in the Mach-O
exports trie.

This change uses a string to track the current trie prefix, instead of a
vector of substrings. Instead of pushing and popping on the vector, the
string is appended and truncated.
