common/block/tcss: Add config for PDC<->PMC mux configuration
Introduce a new Kconfig to enable PD controller to PMC mux configuration. Selecting this config enables direct communication from PDC to PMC. TCSS_HAS_USBC_OPS enables USB-C operations via the EC. When SOC_INTEL_TCSS_USE_PDC_PMC_USBC_MUX_CONFIGURATION is selected, disable TCSS_HAS_USBC_OPS to avoid sending PMC commands from AP/EC. BUG=b:332383540 TEST=USB3 plugged during G3, is detected after system boots from G3.

TCSS uses PDC<->PMC communication to perform mux configuration. When this config is
