ES31: Fix some bugs in ShaderStorageBlockOutputHLSL

When EOpIndexDirect/EOpIndexIndirect/EOpIndexDirectStruct/TIntermSwizzle
appear in [] in ssbo access chain, we should transfer the process of them to
OutputHLSL.

For example:
    instance.v[gl_GlobalInvocationID.x] = data;
    // becomes
    float_Store(dx_instance, 0 + 16 * gl_GlobalInvocationID.x, _data);

    instance.v[s.index[0].x] = data;
    // becomes
    float_Store(dx_instance, 0 + 16 * _s.index[0].x, _data);
