Add owned image views and layout transitions

[antono3]

Summary

• add an owned identity-swizzled 2D image view tied to OwnedImage metadata and lifetime
• add an explicit synchronization-1 image layout transition description and command-buffer recorder
• cover view validation, lifetime metadata, and raw barrier construction; document scope and ordering

Semantics

• callers explicitly provide aspects, layouts, stage masks, access masks, and dependency flags
• the focused helper covers the owned image's single mip level and array layer
• queue-family ownership transfers, broader ranges, and synchronization-2 remain in the raw API

Local validation

• v fmt -verify ergonomic/ergonomic.v ergonomic/ergonomic_test.v
• syntax-only checks for both ergonomic source files
• full compilation delegated to GitHub Actions per repository guidance
