[ruby/json] Drop the leftovers of runtime SSE2 detection
...
Neither the `__builtin_cpu_supports` probe in conf.rb nor `cpuid.h` has a use now that SSE2 is assumed on x86-64. The probe kept SIMD off on GCC older than 4.8, and the `HAVE_CPUID_H` guard broke builds that have `x86intrin.h` but not `cpuid.h` with a redefinition of `find_simd_implementation`.

json: Use SSE2 on x86-64 without checking at runtime
...
__builtin_cpu_supports refers to __cpu_model in compiler-rt, which clang-cl does not link, so generator.so and parser.so failed with an undefined symbol. SSE2 is part of the x86-64 baseline, as NEON is for AArch64, where no check is made either.

[ruby/json] parser.c: Use SWAR to skip consecutive spaces
...
Closes: https://github.com/ruby/json/pull/881
If we encounter a newline, it is likely that the document is pretty printed,
hence that the newline is followed by multiple spaces.
In such case we can use SWAR to count up to eight consecutive spaces at once.

If `load_uint8x16_4` has an external linkage, it is defined in
