change(esp_hw_support): rework ESP32-H4 region protection to the application-owned layout

Browse Source 
The bootloader programs only unlocked PMA entries (no PMP), so the layout is
not a bootloader<->application ABI; the application resets all entries, programs
them in ascending order from IRAM, and locks everything. Verified on ESP32-H4 v0.1.
