Memory leak when spawning entities

Steps to reproduce:
1. Open the attached “EntityGraphicsBug” project
2. Open the “SampleScene” scene
3. Enter Play Mode
4. Press “1” on the keyboard
5. Observe the Task Manager

Expected result: The memory stays the same
Actual result: The memory leaks

Reproducible with: 1.0.0-pre.44 (2022.2.11f1), 1.0.0-pre.65 (2022.2.11f1, 2023.1.0b8, 2023.2.0a6)
Not reproducible with: 1.0.0-pre.15 (2022.2.11f1)
Could not test with: 1.0.0-pre.65 (2020.3.46f1, 2021.3.21f1) (Entities Graphics package requires 2022.1+ Editor version)

Reproduced on: Windows 11 (Intel)
Not reproduced on: macOS Monterey 12.2 (Intel)

Notes:

• Adding “public void OnCreate(ref SystemState state) { throw new System.NotImplementedException(); }

  ” to SimpleMoveSystem and PrefabSpawnerSystem scripts fixes the issue and throws “NotImplementedException: The method or operation is not implemented.” error in the Console

• Comparing before and after memory leak snapshots in Memory Profiler indicates that memory usage climbs in GfxDeviceClient
• The issue is reproducible in both Editor and in a build
