Change executorch binaries (#802)

## Description

This PR changes binaries to include new tokenizer functionalities.

Added: 
- Wordpiece model and decoder
- Bert and Roberta tokenization is supported 
- Padding and truncation from tokenizer.json is now respected 



### Introduces a breaking change?

- [ ] Yes
- [x] No

### Type of change

- [x] Bug fix (change which fixes an issue)
- [ ] New feature (change which adds functionality)
- [ ] Documentation update (improves or adds clarity to existing
documentation)
- [ ] Other (chores, tests, code style improvements etc.)

### Tested on

- [x] iOS
- [x] Android

### Testing instructions
Run the test suites. 
Run all apps that use tokenizers and verify they load and produce proper
output (LLM, S2T, T2I, Embeddings etc.)

### Checklist

- [x] I have performed a self-review of my code

### Additional notes
Running the tests can yield some issues. Couldn't get to why they happen.
Calling failing functions in example apps yields proper results.
Probably some issue with test environment. We decided to not hold this
PR due to failing TC's and investigate them later on.
