simde: update to 0.8.2

0.8.2:
- Start of RISCV64 optimized implementation using the RVV1.0 vector
  extension
- 62 of the ARM Neon intrinsics added in SIMDe 0.8.0 had to be
  removed for not exactly matching the specs and real hardware

0.8.0:
- Complete set of implementations for all NEON intrinsics up from
  56.46%

0.7.6:
- Many minor updates and fixes to NEON, x86, SSE*, and AVX512

0.7.4:
- 40 new NEON families implemented, SVE API implementation started
- Initial support for x86 F16C API
- Initial support for MIPS MSA API
- Initial support for Arm Scalable Vector Extensions (SVE) API
- Initial support for Arm Scalable Vector Extensions (SVE) API
- Initial support for WASM SIMD128 API
- Initial support for the E2K (Elbrus) architecture
- MSVC has many fixes, now compiled in CI using /ARCH:AVX, /ARCH:AVX2,
  and /ARCH:AVX512

devel/simde: Header-only library for SIMD intrinsics

The SIMDe header-only library provides fast, portable implementations
of SIMD intrinsics on hardware which doesn't natively support them,
such as calling SSE functions on ARM. There is no performance penalty
if the hardware supports the native implementation (e.g., SSE/AVX runs
at full speed on x86, NEON on ARM, etc.).
