soc/intel/tigerlake: Add platform wide _OSC capabilities for USB4

This change adds Platform-Wide _OSC capabilities for native USB4
support. There is Engineering Change Request (ECR) with _OSC addition
for OSPM USB support. ACPI section 6.2.11.1.13 is modified with bit 18
as native USB4 support. The OS sets this bit to indicate support for
an OSPM-native USB4 Connection Manager which handles USB4 connection
events and link management. The OS use the _OSC mechanism and the bit
defined in this ECR to obtain configuration and connection management
capabilities of USB4 connections. This change also fixs the byte index
for the DWord-addressable field CDW3 from the capabilities buffer.

BUG=b:140645231
TEST=Check Type C device all ports connection/enumeration with SW CM.
