LOG: [TSan] Fix warning when compiling with -Wmissing-designated-field-initializers (#163401)

Currently we receive a warning when initializing a ThreadEventCallbacks
when compiling with this flag:
```
llvm-project/compiler-rt/lib/tsan/rtl/tsan_platform_mac.cpp:252:3: warning: missing field 'start' initializer [-Wmissing-designated-field-initializers]
  252 |   };
      |   ^
```

This patch explicitly initializes the missing fields to null, fixing the
warning.
