Add "src/rv32_jit.c"

This file is generated by "tools/gen-jit-template.py"

To bring up the Linux Kernel to just-in-time (JIT) compilation, we need
to update the memory-related operation with the memory management unit.
However, the current "src/rv32_jit.c" was generated by the template.
That template reduced the rework for the repeated statements, but also
reduced the flexibility and the intuitiveness for bring up the new
feature. In this commit, we deprecate that template and just use a
regular file for the flexibility.
