Subject: Reland "vboot_logic: Set VB2_CONTEXT_EC_TRUSTED in verstage_main"

This reverts commit adb393bdd6cd6734fa2672bd174aca4588a68016.
This relands commit 6260bf712a836762b18d80082505e981e040f4bc.

Reason for revert:
The original CL did not handle some devices correctly.
With the fixes:
* commit 36721a4 (mb/google/brya: Add GPIO_IN_RW to all variants'
early GPIO tables)
* commit 3bfe46c (mb/google/guybrush: Add GPIO EC in RW to early
GPIO tables)
* commit 3a30cf9 (mb/google/guybrush: Build chromeos.c in verstage

This CL also fix the following platforms:
* Change to always trusted: cyan.
* Add to early GPIO table: dedede, eve, fizz, glados, hatch, octopus,
			   poppy, reef, volteer.
* Add to both Makefile and early GPIO table: zork.

For mb/intel:
* adlrvp: Add support for get_ec_is_trusted().
* glkrvp: Add support for get_ec_is_trusted() with always trusted.
* kblrvp: Add support for get_ec_is_trusted() with always trusted.
* kunimitsu: Add support for get_ec_is_trusted() and initialize it as
	     early GPIO.
* shadowmountain: Add support for get_ec_is_trusted() and initialize
	     it as early GPIO.
* tglrvp: Add support for get_ec_is_trusted() with always trusted.

For qemu-q35: Add support for get_ec_is_trusted() with always trusted.

We could attempt another land.
