Replace assert statements with exceptions

[syedsalman137]

What does this PR do?

I have replaced the assert statements with appropriate exceptions in the directory src/transformers/models/ with all models beginning with a and b letters.

Also, I have corrected error handling at places where except statements were handling AssertionError, even thought it was never to be raised. Here is an example:

try:
    if pointer.shape != array.shape:
        raise ValueError(f"Pointer shape {pointer.shape} and array shape {array.shape} mismatched")
except AssertionError as e:    # Incorrect line
    e.args += (pointer.shape, array.shape)
    raise

I changed the above to:

try:
    if pointer.shape != array.shape:
        raise ValueError(f"Pointer shape {pointer.shape} and array shape {array.shape} mismatched")
except ValueError as e:    # Corrected the line
    e.args += (pointer.shape, array.shape)
    raise

Fixes #12789

Thanks for the fixes! Note that the conversion scripts are exempt form the issue of replacing asserts to exceptions, since they are not really modules of the library.

Some of your modifications break the copied from mechanism. Could you quickly run make fix-copies to fix that?
