arm: [MVE intrinsics] factorize vsrhrq vrshrq

Factorize vsrhrq vrshrq so that they use the same pattern.

	gcc/
	* config/arm/iterators.md (MVE_VSHRQ_M_N, MVE_VSHRQ_N): New.
	(mve_insn): Add vrshr, vshr.
	* config/arm/mve.md (mve_vshrq_n_<supf><mode>)
	(mve_vrshrq_n_<supf><mode>): Merge into ...
	(@mve_<mve_insn>q_n_<supf><mode>): ... this.
	(mve_vrshrq_m_n_<supf><mode>, mve_vshrq_m_n_<supf><mode>): Merge
	into ...
	(@mve_<mve_insn>q_m_n_<supf><mode>): ... this.
