Add option not to print inner graphs in debug_print

import pytensor
import pytensor.tensor as pt
from pytensor.compile.mode import get_default_mode

n = pt.iscalar("n")
x0 = pt.vector("x0")
xs, _ = pytensor.scan(lambda xtm1: xtm1 + 1, outputs_info=[x0], n_steps=n)

mode = get_default_mode().including("scan_save_mem")
fn = pytensor.function([n, x0], xs, mode=mode, on_unused_input="ignore")
fn.dprint()

Subtensor{start:} [id A] 6
 ├─ Scan{scan_fn, while_loop=False, inplace=all} [id B] 5
 │  ├─ n [id C]
 │  └─ SetSubtensor{:stop} [id D] 4
 │     ├─ AllocEmpty{dtype='float64'} [id E] 3
 │     │  ├─ Add [id F] 2

Inner graphs:

Scan{scan_fn, while_loop=False, inplace=all} [id B]
 ← Add [id L]
    ├─ [1.] [id M]
    └─ *0-<Vector(float64, shape=(?,))> [id N] -> [id D]

Want to add an option debug_print(print_inner_graphs=False) that ommits the inner graphs
