[WASM-GC] RTT payload offset is wrong when HAVE(36BIT_ADDRESS)
https://bugs.webkit.org/show_bug.cgi?id=272776
rdar://124477605
Reviewed by Justin Michaud and Yusuke Suzuki.
Fixes RTT::offsetOfPayload() to return the end of the RTT structure instead
of the end of the m_displaySize field. This agrees with the actual address
we compute in RTT::payload(), and fixes a bug where on platforms with 36-bit
addresses, the alignment of RTT causes these two notions of the payload
offset to diverge.
