arm: [MVE intrinsics] factorize vcreateq

We need a 'fake' iterator to be able to use mve_insn for vcreateq_f.

2022-09-08  Christophe Lyon <christophe.lyon@arm.com>

	gcc/
	* config/arm/iterators.md (MVE_FP_CREATE_ONLY): New.
	(mve_insn): Add VCREATEQ_S, VCREATEQ_U, VCREATEQ_F.
	* config/arm/mve.md (mve_vcreateq_f<mode>): Rename into ...
	(@mve_<mve_insn>q_f<mode>): ... this.
	(mve_vcreateq_<supf><mode>): Rename into ...
	(@mve_<mve_insn>q_<supf><mode>): ... this.
