vkd3d-shader/ir: Give more meaningful names to I/O normalisation levels.

The previous names "not normalised" and "fully normalised" have meanings
which are likely to change with time. OTOH including a description of the
normalisation level in the enumerant seems excessive. Relating
normalisation levels to shader model versions might be a reasonable
compromise.

vkd3d-shader/d3dbc: Normalise I/O register write masks when not disassembling.

Sometimes SM1-3 shaders contain write masks that exceed the
signature element masks. That happens because SM1-3 shaders do not
have a concept of signature and signature masks, and OTOH aren't
always able to express any given write mask.

In VSIR we don't want to deal with I/O register masks exceeding the
corresponding signature element mask or usage mask, because, for
instance, for higher shader models it can complicate dealing with
DCL_INDEX_RANGE. In order to have uniform rules for all shader
models we normalise masks coming from SM1-3 shaders.

We don't do that normalisation when disassembling, in order to
preserve the expected output.
