Prior to this commit, when zone.js was included, it wasn't possible to handle `beforeunload`
events correctly if event handlers returned strings to prompt the user.
With this change, we introduce a global configuration flag,
`__zone_symbol__enable_beforeunload`, to allow consumers to enable the default
`beforeunload` handling behavior.
This flag is necessary to prevent any breaking changes resulting from this modification.
The previous attempt to fix it caused a large number of failures in G3. Hence, we're
hiding that fix behind the configuration flag.

This commit fixes an issue where signals in embedded views are not
tracked if they are refreshed with `EmbeddedViewRef.detectChanges`
directly. We had previously assumed that embedded views were always
refreshed along with their hosts.

This is related to an issue that was reported internally. We were assuming that `hasNgModuleMetadataElements` will return true only for property assignments initialized to arrays, but that's not the case.
These changes update the type and our assertions to more accurately reflect the AST and to avoid the error.

Prior to this commit, a memory leak occurred when the `abort` listener was
not removed from the `AbortSignal`. We introduced a fix to remove the event
listener, but it was erroneously stored on the `taskData`, which is a shared
global object. Consequently, when something attempted to remove an event listener,
it immediately removed the last stored abort listener. As a result, events would
never be canceled.
We have now rectified this by storing the remove abort listener function directly on
the task itself. This adjustment ensures that the abort listener is tied only to the
specific task. When the `abort` function is called, it cancels the task. Therefore, it
is safe to associate the cleanup function directly with the task.

Updates the check that prevent writes to template variables in two-way bindings to account for let declarations.
Also fixes some old tests that weren't properly setting up two-way bindings.

Integrates let declarations into the template type checker by producing corresponding constants in the TCB.
This also includes a couple of custom diagnostics to flag usages of let before they're declared and illegal writes to let declarations. We can't rely on TS for these checks, because it includes the variable name in the diagnostic.

This commit updates hydration serialization logic to handle a case when the `withI18nSupport()` call is not present for an application that has a component that uses i18n blocks. Note: the issue is only reproducible for components that also inject `ViewContainerRef`, since it triggers a special serialization code path.
Resolves#56074.

When a consumer switches its liveness state, it gets added to / removed from
the consumer list of all of its producers. This operation is transitive, so
if its producer is *also* a consumer and *its* liveness state is switched,
then the change is applied recursively.
Note that this only matters *if* the producer is also a consumer. However,
the logic in `producerAddLiveConsumer` / `producerRemoveLiveConsumerAtIndex`
coerced the producer node into a producer & consumer node, which allocated
extra arrays into the node structure that are never used. This didn't affect
correctness, but increased the memory usage of plain signal nodes (which are
just producers, never consumers).
This fix changes the logic in those operations to simply check if a producer
is also a consumer instead of coercing it into one.

This makes events bubble! This change also contains changes to
dispatcher and event_dispatcher to make replay synchronous,
so that we avoid odd timing issues. This can be split out though.
Lastly, we have one cleanup change to move the mapping from
event type to functions on the element itself.

Previously, the event replay serialization logic was located before we verify that a `TNode` exists. `TNode`s may not exist in `tView.data` array in several cases, including cases when there is a local ref used on an element: in this case an extra slot in `LView` contains a reference to the same element and `TNode` is not needed. This commit moves the event replay serialization logic a bit lower, after we check for TNode presence.
