apacheGH-41400: [MATLAB] Bump libmexclass version to commit ca3cea6 (apache#41436)

### Rationale for this change

@ kevingurney and I recently resolved multiple issues related to `mathworks/libmexclass` not supporting ARM-based macOS builds (i.e. builds on `macos-14`):

- mathworks/libmexclass#76
- mathworks/libmexclass#77

We should bump the version of mathworks/libmexclass used by the MATLAB interface to the latest available commit ([ca3cea6](mathworks/libmexclass@ca3cea6) as of now) in order to enable building the MATLAB interface to Arrow on `macos-14` (which is ARM-based).

### What changes are included in this PR?

- Bumped version of `mathworks/libmexclass` used by the MATLAB interface to [ca3cea6](mathworks/libmexclass@ca3cea6)

### Are these changes tested?

- Yes. The existing test points verify verify upgrading `mathworks/libmexclass` does not break the MATLAB interface.

### Are there any user-facing changes?

- No. 

### Future Directions

- apache#41435
- apache#41385
