Fix fgRemoveUnreachableBlocks to detect all changes (#57199)

When 'removing' a BBF_DONT_REMOVE block we change it to BBJ_THROW. After
this it is possible that other blocks become unreachable, so we should
keep looking for such blocks.

In #57061 that manifested in a case where the unreachable block did not
have SSA built for it, but downstream the compiler was relying on SSA
being built.

Fix #57061
