LoongArch: kdump: Add single kernel image implementation
This feature depends on the kernel being relocatable.
Enable using single kernel image for kdump, and then no longer need to
build two kernels (production kernel and capture kernel share a single
kernel image).
Also enable CONFIG_CRASH_DUMP in loongson3_defconfig.
