[ptr-compr] Mark/sweep EPT for array buffers when sandbox disabled In the configuration where you have V8_COMPRESS_POINTERS but not V8_ENABLE_SANDBOX, most external pointers are encoded directly instead of via handles to entries in the ExternalPointerTable. However, array buffer extensions are unlike other ExternalPointerSlots in that they get EPT entries even when the sandbox is disabled. This patch enables the mark/sweep/compact machinery for external pointer tables in this configuration. Based on patch by Kenton Varda <kenton@cloudflare.com>.
