TF implementation of RegNets (#17554)

* chore: initial commit

Copied the torch implementation of regnets and porting the code to tf step by step. Also introduced an output layer which was needed for regnets.

* chore: porting the rest of the modules to tensorflow

did not change the documentation yet, yet to try the playground on the model

* Fix initilizations (#1)

* fix: code structure in few cases.

* fix: code structure to align tf models.

* fix: layer naming, bn layer still remains.

* chore: change default epsilon and momentum in bn.

* chore: styling nits.

* fix: cross-loading bn params.

* fix: regnet tf model, integration passing.

* add: tests for TF regnet.

* fix: code quality related issues.

* chore: added rest of the files.

* minor additions..

* fix: repo consistency.

* fix: regnet tf tests.

* chore: reorganize dummy_tf_objects for regnet.

* chore: remove checkpoint var.

* chore: remov unnecessary files.

* chore: run make style.

* Update docs/source/en/model_doc/regnet.mdx

* chore: PR feedback I.

* fix: pt test. thanks to @ydshieh.

* New adaptive pooler (#3)

* feat: new adaptive pooler

* chore: refactored __init__.

* chore: copied from -> taken from./g

* adaptive pool -> global avg pool, channel check.

* chore: move channel check to stem.

* pr comments - minor refactor and add regnets to doc tests.

* Update src/transformers/models/regnet/modeling_tf_regnet.py
