#14190: Convert all functions in schemes.elliptic_curves.ell_rational_field.py
that
use caching to use @cached_method
-------------------------------+--------------------------------------------

-------------------------------+--------------------------------------------
Some functions in schemes.elliptic_curves.ell_rational_field.py that
implement caching were written before the `@cached_method` decorator came
to be, for example the `modular_degree()` method:
{{{
def modular_degree(self, algorithm='sympow'):
r"""
...
"""
try:
return self.__modular_degree
except AttributeError:
...
}}}
This patch would rework those functions to use `@cached_method` and
eliminate the unnecessary try/except clauses etc.
