mb/google/zork: Add helpers for v3 schematics and wifi power enable

This change adds following two helper functions:
1. variant_uses_v3_schematics() - Check whether the variant is using
v3 version of schematics.
2. variant_has_active_low_wifi_power() - Check whether the variant is
using active low power enable for WiFi.

In addition to this, Kconfig options are reorganized to add two new
configs - VARIANT_SUPPORTS_PRE_V3_SCHEMATICS and
VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH. This allows the helper
functions to return `true` early without checking for board version.

Eventually, when a variant decides to drop support for pre-v3
schematics, it can be dropped from selecting
VARIANT_SUPPORTS_PRE_V3_SCHEMATICS. Similarly, when the variant
decides to drop support for active high power enable for WiFi, it can
be dropped from selecting VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH.
