Write access to the shared memory region is required because JavaScript lacks the capability to create read-only ArrayBuffers. When a user attempts to modify an ArrayBuffer that utilizes a ReadOnlySharedMemoryRegion as its BackingStore it triggers an access violation. Note that this pull request may be reverted in the future if JavaScript adds read-only ArrayBuffer support.
