Add SVE implementation for sdot/ddot
...
This adds an SVE implementation to sdot/ddot when available, falling back to the previous Advanced SIMD kernel where there's no SVE implementation for the kernel.
All the targets were essentially treating `dot_thunderx2t99.c` as the Advanced SIMD implementation so I've renamed it to better fit with the feature detection.

Remove unnecessary instructions from Advanced SIMD dot
...
The existing kernel was issuing extra instructions to organise the arguments into the same registers they would usually be in and similarly to put the result into the appropriate register.
This has an impact on smaller sized dots and seemed like a quick fix

Add [cz]scal microkernels for SKYLAKEX
...
These are as similar to dscal_microk_skylakex-2.c as possible
for consistency.
Note that before this change SKYLAKEX+ uses generic C functions for
cscal/zscal via commit 2271c350 from #2610 (which is masked by
commit 086d87a30 ). However now #3799 disables FMAs (in turn enabled
by `-march=skylake-avx512`) in the plain C code which fixes excessive
LAPACK test failures more nicely.

x86_64: prevent GCC and Clang from generating FMAs in cscal/zscal.
...
If e.g. -march=haswell is set in CFLAGS, GCC generates FMAs by default, which
is inconsistent with the microkernels, none of which use FMAs. These
inconsistencies cause a few failures in the LAPACK testcases, where
eigenvalue results with/without eigenvectors are compared.
Moreover using FMAs for multiplication of complex numbers can give surprising
results, see 22aa81f for more information.
This uses the same syntax as used in 22aa81f for zarch (s390x).

POWER: Fix complex dot function failures
...
There are some test failures in complex dot functions when compiling with gcc12.
The machine constraints used now do not update all the four elements in the
expected result array. Fixing this with a reduced level of optimization.
This is not changing any performance numbers but will be converted to C code in future.
