build-type: debug; `optimize: off` instead of `optimize: debug`

[ReinhardKeil]

Describe the bug
Several ST packs contain templates that specify for build-type: debug; optimize: off instead of optimize: debug

Example: https://github.com/Open-CMSIS-Pack/STM32C0xx_DFP/blob/main/Templates/CubeMX/CubeMX.csolution.yml#L37

This problem should be corrected for the next release.

I have corrected optimize level from optimize: none to optimize: debug in all ST DFPs (24 packs) templates.
