loongarch/kexec: refactor for kernel/Kconfig.kexec
The kexec and crash kernel options are provided in the common kernel/Kconfig.kexec. Utilize the common options and provide the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the equivalent set of KEXEC and CRASH options.

- kexec is a system call that implements the ability to shutdown your
- current kernel, and to start another kernel. It is like a reboot
- but it is independent of the system firmware. And like a reboot
- you can start any kernel with it, not just Linux.

- Generate crash dump after being started by kexec. This should
- be normally only set in special crash dump kernels which are
- loaded in the main kernel with kexec-tools into a specially
