Extract common linker scripts

[xuchang-vivo]

That every board has their own linker scripts is error-prone and trivial.

Separating linker scripts into every arch may be a better choice, like https://github.com/zephyrproject-rtos/zephyr/blob/main/include/zephyr/arch/arm/cortex_m/scripts/linker.ld

In addition, giving a args to let people specify their own linker scripts.

AFAIK, esp32 idf assembles linker scripts at compile time for each platform it supports.
