  -----------
  [AArch64] Remove VK_WEAKREF from arm64ec lowering. (#141717)

VK_WEAKREF doesn't actually do anything anymore, and it was never really
necessary. We set a bit on the MCSymbol to represent the anti-dep
semantics.

This patch doesn't delete the VK_WEAKREF enum value because that causes
an unrelated issue in CodeGen/AArch64/wineh-try-catch.ll.
