[RISC-V] Improve RVV kernel generator LMUL usage
...
The RVV kernel generation script uses the provided LMUL to increase the number of accumulator registers.
Since the effect of the LMUL is to group together the vector registers into larger ones, it actually should be used as a multiplier in the calculation of vlenmax.
At the moment, no matter what LMUL is provided, the generated kernels would only set the maximum number of vector elements equal to VLEN/SEW.
Commit changes the use of LMUL to properly adjust vlenmax. Note that an increase in LMUL results in a decrease in the number of effective vector registers.

Current RVV x280 target depends on vlen=512-bits for Level 3 operations.
Commit adds generic target that supports vlen=128-bits.
New target uses the same scalable kernels as x280 for Level 1&2 operations, and autogenerated kernels for Level 3 operations.
Functional correctness of Level 3 operations tested on vlen=128-bits using QEMU v8.1.1 for ctests and BLAS-Tester.

Use _mm_set1_epi{32,64x} to init mask in x86-64 [cz]asum
...
for skylake kernels. This is the same method as used in [sd]asum.
_mm_set1_epi64x was commented out for zasum, but has the advantage
of avoiding possible undefined behaviour (using an uninitialized
variable), optimized out by NVHPC and icx. The new code works
fine with those compilers.
For GCC 12.3 the generated code is identical; no matter what method
you use, the compiler optimizes the code into a compile-time
constant, there is no performance benefit using mm_cmpeq_epi8
since the corresponding instruction (VPCMPEQB) isn't actually
generated!

Fix casum fallback kernel.
...
This kernel is only used on Skylake+ if the kernel with AVX512
intrinsics can't be used, but used the variable x1 incorrectly
in the tail end of the loop, as it is still at the initial
value instead of where x points to.
This caused 55 "other error"s in the LAPACK tests
(https://github.com/OpenMathLib/OpenBLAS/issues/4282 )
This change makes casum.c as similar as possible as zasum.c,
because zasum.c does this correctly.
