Update cmake build 3rd party path for Llama Project (#9162)

### Summary
The abseil-cpp, re2, and sentencepiece paths needed to be updated from
`extension/llm/third-party/<3P_package>` to
`extension/llm/tokenizers/third-party/<3P_package>`.

This is due to the change in location from
2094659

### Test plan
Before:
- Receive the following error when building:
`<path>/llama-stack-client-swift/local_inference/executorch/extension/llm/third-party/abseil-cpp"
does not exist`

After: 
- Build successful
