Growing memory usage in web_protocol.py

### Describe the bug

I've been seeing a memory leak on one of our services, when running `tracemalloc`, one of the patterns I can see is that the memory usage in `web_protocol.py` keeps growing when being compared against the first snapshot. See below.

I'm wondering if it's a known issue that `web_protocol.py` isn't cleaning up ?

```

The traceback for that line is

```
File "/usr/local/lib/python3.10/site-packages/aiohttp/web_protocol.py", line 380
messages, upgraded, tail = self._request_parser.feed_data(data)
```

### To Reproduce

I think from a simple application like this will show the growing memory usage in `web_protocol.py`. I was just sending images to the `/image` enpdoint.

```
from aiohttp import web
import gc
import asyncio
import tracemalloc
from time import time

import objgraph

import tracemalloc

# list to store memory snapshots
snaps = []

def snapshot():
snaps.append(tracemalloc.take_snapshot())

def display_stats():
stats = snaps[0].statistics('filename')
print("\n*** top 5 stats grouped by filename ***")
for s in stats[:5]:
print(f"\n{str(s)}")

def compare():
first = snaps[0]
for snapshot in snaps[1:]:
stats = snapshot.compare_to(first, 'lineno')
print("\n*** top 10 stats ***")
for s in stats[:10]:
print(f"\n{str(s)}")

def print_trace():
# pick the last saved snapshot, filter noise
snapshot = snaps[-1].filter_traces((
tracemalloc.Filter(False, ""),
tracemalloc.Filter(False, ""),
tracemalloc.Filter(False, ""),
))
largest = snapshot.statistics("traceback")[0]

print(f"\n*** Trace for largest memory block - ({largest.count} blocks, {largest.size/1024} Kb) ***")
for largestt in largest.traceback.format():
print(f"\n{str(largestt)}")

async def hanlder(request):
print(f'read request')
req = await request.json()
return web.Response(text="Request has been receieved")

async def on_startup(app) -> None:
asyncio.create_task(show_memory())

async def show_memory():
print('start tracing memory')

tracemalloc.start(10)
start = tracemalloc.take_snapshot()

snapshot_num = 1
while True:
for _ in range(10):
await asyncio.sleep(2)

gc.collect()
snapshot()

display_stats()
compare()
print_trace()

my_web_app = web.Application()
my_web_app.router.add_route('POST', '/image', hanlder)
my_web_app.on_startup.append(on_startup)
web.run_app(my_web_app)
```

### Expected behavior

That the memory being used in `web_protocol.py` gets cleaned up.

### Logs/tracebacks

```python-traceback

```
