Subject: [PATCH 1/9] [Snippets] Add final Linear IR dump capability with
 subgraph naming

Add support for dumping final Linear IR right before code generation using the existing OV_SNIPPETS_DUMP_LIR debug capability.

 - Extend OV_SNIPPETS_DUMP_LIR to support "final" pass name for capturing the final state of Linear IR before code generation
 - Add name_modifier option to include subgraph friendly names in dump filenames
 - Sanitize subgraph names by replacing '/' and ':' with '_' for filesystem compatibility
 - Update LIRPassDump to support optional name prefix for better file identification when multiple subgraphs are present

Usage:
```bash
OV_SNIPPETS_DUMP_LIR="passes=final name_modifier=subgraph_name" binary
```
