LoongArch64: using getauxval to do runtime check
...
Using the getauxval instruction can prevent errors
caused by hardware supporting vector instructions
while the kernel does not support them

Use SVE zgemm/cgemm on Arm(R) Neoverse(TM) V1 core
...
This patch removes the prefetches from cgemm/zgemm which improves the performance similar to sgemm/dgemm did in #3868 , this means I'm happy to enable this on any applicable cores.
I also replicated the unrolling the copies from sgemm and dgemm.

Whilst disambiguating whilelt, I inadvertantly used the wrong datatype
for offsets, which can be negative. This rectifies that.

Add documentation on redistributing OpenBLAS
...
This touches on the following:
- build configurations
- naming of symbols, shared/static libraries and other build outputs
like pkg-config and CMake files
- (in more detail) guidance on ILP64 builds
It tries to explain that, while this is only guidance and there may be
reasons to deviate from that, for some build options there are best
practices, and for some others there are choices to make.
It also links to a number of well-maintained build recipes in order
to help packagers of other distros make choices.
Closes gh-3798

Add ARMV8SVE to AArch64 Dynamic Dispatch
...
In order to enable support for future cores which have similar tunings
(in this case I'm doing this for the Arm(R) Neoverse(TM) V2 core), this generically detects SVE support and enables it. This should better manage the size and complexity of dynamic dispatch rather than just copy pasting the same parameters.
To make `ARMV8SVE` more representive of the common 128-bit SVE case,
I've split it and similar parameters from A64FX which has the wider
512-bit SVE.

These are generally better and, in some cases, include threading which helps in the cores we're targeting here.
