**Summary**
GeneratedField ignores null=False on MySQL - columns are always nullable

**Description**
When creating a GeneratedField with null=False on MySQL, the database
column is always created as nullable, ignoring the null=False parameter.
Steps to Reproduce

{{{
pythonfrom django.db import models

class MyModel(models.Model):
area = models.GeneratedField(
.....
null=False, # ← Ignored
)
}}}


- The migration file removes null=False from GeneratedField definition
- Even if manually added to migration file, Django doesn't apply NOT NULL
constraint to database
