Measure custom Dasharo firmware setting as part of Measured Boot

[macpijan]

The problem you're addressing (if any)

Dasharo options, such as: https://docs.dasharo.com/dasharo-menu-docs/dasharo-system-features/ are not measured as part of Measured Boot process - change in these do not result in any PCR change.

Describe the solution you'd like

Some (PCR1?) PCR reflect change in Dasharo settings

Where is the value to a user, and who might that user be?

Changing crucial options, such as flash lock, should be reflected in PCRs

Describe alternatives you've considered

Measured variables:

• IommuConfig
• LockBios
• MeMode
• OptionRomPolicy
• SmmBwp (SMM BIOS write protection)

They are measured to PCR-1 with event type of 0x00DA0000 (not sure if any was already used for Dasharo). Variable data is hashed and log entry contains variable name, \0 and then variable data.
