payloads/depthcharge: Add default 64-bit libpayload config

Add CONFIG_LP_DEFCONFIG_OVERRIDE_X64 flag to select default 64-bit
config file in payloads/libpayload/configs directory.

This is used in standalone environment. The existing libpayload
deconfig file is for boards with 32-bit format and deconfig_64
file is added for 64-bit without adding specific
board.[board name] file in libpayload.

BUG=none
TEST=Build with this new flag and check that the libpayload and
depthcharge.elf are built in 64-bit format.
