softpipe: Enable PIPE_CAP_TEXTURE_BUFFER_OFFSET_ALIGNMENT

Browse Source 
The offset alignment must be set to s16 because the tile cache is
implemented to require this.

This enables ARB_buffer_texture_range and OES_texture_buffer for
softpipe. The according deqp-gles31 tests pass.

Also update the feature table.
