Replace ReadOnlySharedMemoryRegion with WritableSharedMemoryRegion (see #3502)

Browse Source 
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.
