Summary: This change expands the amount of registers stashed by the entry and `__xray_CustomEvent` trampolines. We've found that since the `__xray_CustomEvent` trampoline calls can show up in situations where the scratch registers are being used, and since we don't typically want to affect the code-gen around the disabled `__xray_customevent(...)` intrinsic calls, that we need to save and restore the state of even the scratch registers in the handling of these custom events.
