google/caroline: Add as a variant of glados

Add google/caroline (Samsung Chromebook Pro) as a variant of
glados Skylake reference board:
- add caroline-specific DPTF, EC config, GPIO config, Kconfig,
    NHLT config, PEI data, VBT, SPD data, and devicetree
- add caroline-specific memory-init param to romstage
- adjust mainboard EC SCI events for boards with tablet function

Adapted from Chromium branch firmware-glados-7820.B, commit
b0c3efe54d877246d07f2467b2dff51cc30348fa [soc/intel/skylake: Enable VMX]

Test: build/boot google/caroline, verify correct functionality
