agx: Implement nir_op_txb
Like explicit LODs, biases must be 16-bit, so add a lowering rule for
this. With the LOD mode selection updated for txb, we can then ingest
biases like explicit LODs and allowlist txb. Passes:
dEQP-GLES2.functional.shaders.texture_functions.fragment.texture2d_bias
dEQP-GLES2.functional.texture.mipmap.2d.bias.*
