bootconfig: Default BOOT_CONFIG_FORCE to y if BOOT_CONFIG_EMBED

When a kernel is built with CONFIG_BOOT_CONFIG_EMBED=y, the intention
will normally be to unconditionally provide the specified kernel-boot
arguments to the kernel, as opposed to requiring a separately provided
bootconfig parameter.  Therefore, make the BOOT_CONFIG_FORCE Kconfig
option default to y in kernels built with CONFIG_BOOT_CONFIG_EMBED=y.

The old semantics may be obtained by manually overriding this default.
