This PR removes the dependency on langcodes introduced in #9342.
While the introduction of langcodes allows a significantly wider range of language codes, there are some unexpected side effects:
zh-Hant (Traditional Chinese) should be mapped to zh intead of None, as spaCy's Chinese model is based on pkuseg which supports tokenization of both Simplified and Traditional Chinese.
Since it is possible that spaCy may have a model for Norwegian Nynorsk in the future, mapping no (macrolanguage Norwegian) to nb (Norwegian Bokmål) might be misleading. In that case, the user should be asked to specify nb or nn (Norwegian Nynorsk) specifically or consult the doc.
Same as above for regional variants of languages such as en_gb and en_us.
Overall, IMHO, introducing an extra dependency just for the conversion of language codes is an overkill. It is possible that most user just need the conversion between 2/3-letter ISO codes and a simple dictionary lookup should suffice.
With this PR, ISO 639-1 and ISO 639-3 codes are supported. ISO 639-2/B (bibliographic codes which are not favored and used in ISO 639-3) and deprecated ISO 639-1/2 codes are also supported to maximize backward compatibility.

* Add spacy.TextCatParametricAttention.v1
This layer provides is a simplification of the ensemble classifier that
only uses paramteric attention. We have found empirically that with a
sufficient amount of training data, using the ensemble classifier with
BoW does not provide significant improvement in classifier accuracy.
However, plugging in a BoW classifier does reduce GPU training and
inference performance substantially, since it uses a GPU-only kernel.
* Fix merge fallout
* Add TextCatReduce.v1
This is a textcat classifier that pools the vectors generated by a
tok2vec implementation and then applies a classifier to the pooled
representation. Three reductions are supported for pooling: first, max,
and mean. When multiple reductions are enabled, the reductions are
concatenated before providing them to the classification layer.
This model is a generalization of the TextCatCNN model, which only
supports mean reductions and is a bit of a misnomer, because it can also
be used with transformers. This change also reimplements TextCatCNN.v2
using the new TextCatReduce.v1 layer.

* Update `TextCatBOW` to use the fixed `SparseLinear` layer
A while ago, we fixed the `SparseLinear` layer to use all available
parameters: https://github.com/explosion/thinc/pull/754
This change updates `TextCatBOW` to `v3` which uses the new
`SparseLinear_v2` layer. This results in a sizeable improvement on a
text categorization task that was tested.
While at it, this `spacy.TextCatBOW.v3` also adds the `length_exponent`
option to make it possible to change the hidden size. Ideally, we'd just
have an option called `length`. But the way that `TextCatBOW` uses
hashes results in a non-uniform distribution of parameters when the
length is not a power of two.
* Replace TexCatBOW `length_exponent` parameter by `length`
We now round up the length to the next power of two if it isn't
a power of two.
* Remove some tests for TextCatBOW.v2
* Fix missing import
* Add note on score_weight if using a non-default span_key for SpanCat.
* Fix formatting.
* Fix formatting.
