arm: [MVE intrinsics] add load_gather_base shape
This patch adds the load_gather_base shape description.
Unlike other load_gather shapes, this one does not support overloaded
forms.
gcc/ChangeLog:
* config/arm/arm-mve-builtins-shapes.cc (struct
load_gather_base_def): New.
* config/arm/arm-mve-builtins-shapes.h: (load_gather_base): New.
