[BUG]: Performance Optimization Proposal: QNX Message Passing for Local Communication

### vSomeip Version

v3.1.20

### Boost Version

v1.72

### Environment

8295 QNX

### Describe the bug

Issue Summary
The current vsomeip implementation uses Unix Domain Socket (UDS) for intra-domain communication on QNX platform, which causes significant CPU overhead in production environments. We propose implementing QNX native Message Passing as an alternative to improve performance.

### Reproduction Steps

_No response_

### Expected behaviour

_No response_

### Logs and Screenshots

_No response_

No files, tests, or entry points are named. Start by locating the QNX-specific Unix Domain Socket implementation and the intra-domain communication path, then review how QNX native Message Passing could fit. Done would require an implemented alternative for QNX 8295 and evidence that it reduces the reported CPU overhead.
