drivers: wifi: added Infineon AIROC WIFI driver

Added initial version of Infineon AIROC WIFI  driver

Added initial version of binding file for Infineon AIROC WIFI
driver

Rename CONFIG_ABSTRACTION_RTOS_COMPONENT_ZEPHYR to
CONFIG_USE_INFINEON_ABSTRACTION_RTOS

Exclude cy8cproto_062_4343w platform from
drivers.modem.esp_at.build test

Change revision hal_infineon to
69c883d3bd9fac8a18dd8384624b8c472a68d06f
