Subject: [PATCH] dev-cpp/simdutf: add 9.2.1,use-flag enable build of atomic
 base64 API

Bump simdutf with changes as described below.

The nodejs dependency V8 requires newer simdutf atomic base64 APIs that are
not provided by simdutf by default.

The following functions are expected:
simdutf::atomic_binary_to_base64
simdutf::atomic_base64_to_binary_safe (char and char16_t)

Simdutf provides these functions when compiled with C++20 and
-DSIMDUTF_ATOMIC_REF defined.

Gate this functionality behind a new local use flag (atomic-base64).
