Xi Ruoyao b46de72c26 LoongArch64 assembly pack: Fix ChaCha20 ABI breakage 
The [LP64D ABI][1] requires the floating-point registers f24-f31
(aka fs0-fs7) callee-saved.  The low 64 bits of a LSX/LASX vector
register aliases with the corresponding FPR, so we must save and restore
the callee-saved FPR when we writes into the corresponding vector
register.

This ABI breakage can be easily demonstrated by injecting the use of a
saved FPR into the test in bio_enc_test.c:

    static int test_bio_enc_chacha20(int idx)
    {
        register double fs7 asm("f31") = 114.514;
        asm("#optimize barrier":"+f"(fs7));
        return do_test_bio_cipher(EVP_chacha20(), idx) && fs7 == 114.514;
    }

So fix it.  To make the logic simpler, jump into the scalar
implementation earlier when LSX and LASX are not enumerated in AT_HWCAP,
or the input is too short.
