Updated docs with the new SIMD macros, added a release note for SIMD to_chars.

Also clarified the meaning of BOOST_UUID_USE_AVX10_1 in the docs as the previous
wording could be taken that it indicates support for a subset of AVX-512 that
is supported in Skylake-X.

* Added a `noexcept` `operator()` overload to `string_generator`.
* `string_generator` now supports the Unicode character types in addition to `char` and `wchar_t`.
* Most `uuid` accessors, operations, and `to_chars` are now `constexpr` when possible (on {cpp}14 and higher and on recent compilers).
* Added SIMD implementation of `to_chars`, which can offer up to 5.5x performance improvement in UUID formatting.

The library does not require 512-bit vectors and is compatible with CPUs implementing AVX-512F, CD, VL, BW and DQ instruction subsets (i.e. equivalent to Intel Skylake-X).
When defined by user, this macro indicates support for the full set of instructions defined in AVX10.1. Currently, the library does not require 512-bit vectors and is compatible with CPUs implementing AVX-512F,
CD, VL, BW and DQ instruction subsets (i.e. equivalent to Intel Skylake-X), so it may auto-detect and use AVX-512 even if only those subsets are supported.
