[AArch64] Rename SVE shape "unary_count" to "unary_to_uint"

The SVE ACLE shape names use "_int" and "_uint" for arguments that are
signed-integer or unsigned-integer variants of the main vector type.
With SVE2 this variation also becomes common for return values,
which the main SVE2 patch handles using "_to_int" and "_to_uint".
This patch renames the existing unary_count shape to match the
new scheme.
