  [ARM] Fix VBICimm and VORRimm generation under Big endian. (#107813)

This is a smaller follow on to #105519 that fixes VBICimm and VORRimm
too. The logic behind lowering vector immediates under big endian
Neon/MVE is to treat them in natural lane ordering (same as little
endian), and VECTOR_REG_CAST them to the correct type (as opposed to
creating the constants in big endian form and bitcasting them). This
makes sure that is done when creating VORRIMM and VBICIMM.
