[AArch64] Generalise aarch64_simd_valid_immediate for SVE
The current aarch64_simd_valid_immediate code predates the move
to the new CONST_VECTOR representation, so for variable-length SVE
it only handles duplicates of single elements, rather than duplicates
of repeating patterns.
This patch removes the restriction. It means that the validity
of a duplicated constant depends only on the bit pattern, not on
the mode used to represent it.
The patch is needed by a later big-endian fix.

gcc/
* config/aarch64/aarch64.c (aarch64_simd_valid_immediate): Handle
all CONST_VECTOR_DUPLICATE_P vectors, not just those with a single
duplicated element.
