Remove deprecated eSPI memory map

[williampMSFT]

The eSPI memory map is no longer in use, so this change removes it to simplify. As part of this, also remove examples that were intended to exercise the now-removed functionality.

Resolves #692

Pull request overview

This pull request removes the deprecated eSPI memory map infrastructure and associated example code that exercised it. The memory map was previously used to expose EC (Embedded Controller) data structures to the host via eSPI, but this functionality is no longer needed.

Changes:

• Removed entire ec_type module from embedded-service, including structures, messages, and code generation scripts for the memory map
• Deleted three example binaries that demonstrated the removed memory map functionality
• Simplified espi-service to remove memory map buffer parameter and related initialization code
• Added battery-service-messages dependency to example projects as a replacement for the removed message types

I'm aligned with this change, but just want an approval from @jerrysxie before this goes in.

Whoops, sorry, just saw this after I hit the merge button - fwiw I did chat with Jerry offline before sending this out and he said he's onboard with removing the examples that were leveraging the memory map, so I think we're good here, but I'll mention it in the standup tomorrow and we can revert if there are concerns
