128-bit formats (RGBA32) are emulated as two stacked G32R32 planes. The bound sampler reads the RG plane and a companion sampler reads the BA plane, which etna_nir_lower_128bit(..) reassembles in the shader. Only the descriptor path set up the companion, so the state path could not sample these formats. Set up the companion on the state path too and share companion_slot(..) between both paths. The real requirement is the plane format, not the descriptors. The float plane G32R32F samples through the half-float pipe, so gate it on HALF_FLOAT and advertise GL_OES_texture_float, also on halti2 GPUs like GC3000. The integer plane G32R32I needs halti5, so keep the integer formats there. The KHR-GLES2 internalformat tests for sized RGB32F/RGBA32F need an ES3 context, so list them as expected fails on GC3000 too. Verified on GC7000 with and without ETNA_MESA_DEBUG=no_texdesc.
