[FPGA] MASK_ROM/ROM_EXT exec_environments require info flash page initialization

[moidx]

Description

Issue

Currently, the flash_ctrl and keymgr may raise alerts due to the initial info flash configuration when booting with the mask_rom and rom_ext targets.

• The keymgr requires the Owner and Secret owner pages to be initialized.
• Ownership transfer requires the owner block to be initialized.

Options

1. Modify all environments using the real rom_ext so that there is an initial bootstrap operation with the personalization image to initialize all required info partitions. Applicable to all FPGA configurations.
2. Register a weak functions in the rom_ext to initialize the owner partition for silicon targets already deployed in various environments.

I think it may be more efficient to go with option 2, since it could be much lighter weight than running a full personalization on every boot, since we really just need to program those two pages.

yes, another option is splicing, the only downside with splicing is it will require a lot more infrastructure than a weak function in the ROM_EXT
