aarch64: Fix up *add<mode>3_poly_1 [PR99813]
As mentioned in the PR, Uai constraint stands for
aarch64_sve_scalar_inc_dec_immediate
while Uav for
aarch64_sve_addvl_addpl_immediate.
Both *add<mode>3_aarch64 and *add<mode>3_poly_1 patterns use
* return aarch64_output_sve_scalar_inc_dec (operands[2]);
* return aarch64_output_sve_addvl_addpl (operands[2]);
in that order, but the former with Uai,Uav order, while the
latter with Uav,Uai instead. This patch swaps the constraints
so that they match the output.

PR target/99813
* config/aarch64/aarch64.md (*add<mode>3_poly_1): Swap Uai and Uav
constraints on operands[2] and similarly 0 and rk constraints
on operands[1] corresponding to that.
* g++.target/aarch64/sve/pr99813.C: New test.
