[bmalloc] Fix misalignment issue for seedPtr in TZoneHeapManager::init()
https://bugs.webkit.org/show_bug.cgi?id=285544
rdar://142489488
Reviewed by Yusuke Suzuki.
The 8-byte pointer `seedPtr` in TZoneHeapManager::init() is used
to copy 8 bytes from `seed` each time. This patch ensures that `seed`
is 8-byte aligned to mitigate the misalignment issue and prevent
undefined behavior during pointer dereferencing.
