Go To Definition does not work inside python REPL

[bhavyaus]

Testing #23484

Steps:

1. Create a python file and include the below sample code:

def is_prime(n):
    """Check if a number is prime."""
    if n <= 1:
        return False
    if n <= 3:
        return True
    if n % 2 == 0 or n % 3 == 0:
        return False
    i = 5
    while i * i <= n:
        if n % i == 0 or n % (i + 2) == 0:
            return False
        i += 6
    return True

def generate_primes(limit):
    """Generate a list of prime numbers up to a given limit."""
    primes = []
    for num in range(limit):
        if is_prime(num):
            primes.append(num)
    return primes

limit = 100
primes = generate_primes(limit)
print(f"Prime numbers up to {limit}: {primes}")
print('Hellp World!')

2. Select the entire contents of the file and run in Python REPL
3. In the Python REPL cell, right click on generate_primes(limit) and use Go To Definition command.
4. Expected cursor to jump to the generate_primes definition but the operation results in a no-op

Just gave this a try with both Python REPL and Interactive Window but I dont think Go To Definition works on either.
/cc @amunger Should I transfer this to Pylance or Jupyter?

This might be fixed once we switch to a notebook model with microsoft/vscode#154983.
Either way, probably not worth actually fixing until that is done since it would probably change what is needed.

this almost works now, but the cell input needs to be expanded within the REPL.
