MacOS Troubleshooting - Rewrite section names macOS

Description

This PR introduces a cross-platform, rewrite step that normalizes section names inside the generated file: generated//static_parameters.zig

When XIP (Execute-In-Place) is enabled, the generated static_parameters.zig may contain Mach-O section names:

• __DATA,__flash_weights
• __TEXT,__const

These are valid only on macOS (Mach-O), but break builds when targeting boards.
This caused build/linker errors as soon as XIP was enabled on non-macOS platforms.

What this adds:
A small host-side tool (rewrite_sections.zig) that:

• Scans static_parameters.zig.
• Detects platform-specific section names.
• Rewrites them into universally valid ELF-compatible names:
  - __DATA,__flash_weights → .flash_weight
  - __TEXT,__const → .rodata
• A clean and isolated build step integrated into build.zig, placed after codegen and before static library compilation.
• The tool automatically inherits the correct optimization mode and runs only when XIP is enabled, preserving performance and build determinism.

Checklist

• My code follows the project's coding style guidelines.
• I have performed a self-review of my own code.
• All existing tests pass.

Testing

The idea was simple:

• When XIP is enabled + target is ELF → rewrite must run
• Otherwise → rewrite step must be skipped and nothing changes
  So I tested the two scenarios and the rewrite step works as intended.
