Memory access violation in LightProbesManager when appending LightProbes objects with overlaps twice

Steps to reproduce:
1. Open the attached project (JapanOffice.zip);
2. In the opened popup window for prompting to change Project setting press Cancel button;
3. Ensure that in the Hierarchy there are several scenes loaded additively; if there are none, load those scenes manually;
4. In the Hierarchy select any scene other than the active scene (e.g. NoonB) and double-click on it;
5. Repeat step 4 5-6 times;
6. Enter Play mode.

Expected result: Play mode launches without crashes.
Actual result: Editor crashes

Reproducible with: 2021.2.0b15, 2021.2.4f, 2022.1.0a9, 2022.1.0a16
Not reproducible with: 2019.4.33f1, 2020.3.23f1, 2021.2.0b14, 2022.1.0a8

Notes:

• Reproducible on Windows (by following the repro steps) and macOS (after just opening the repro project);
• The crash might not reproduce every time; if it doesn't try exiting Play mode after step 6 or repeat the initial steps once again with different timings between actions;
• The crash might produce different stack traces on different versions.
• First few lines of a stacktrace:

Probable Root Cause:
When reproing this we found what seemed like random callstack at each crash. Further investigation suggests that this is because LightProbesManager#Append() can write beyond the range of its allocated memory (see the memcpy involving m_BakedCoefficients inside Append()). By doing this it effectively caused undefined behaviour (including sometimes crashing the editor).
