Bug 40429: Update Onboarding for 10.5

- adds new v2 deprecated warning page (js and styling) that piggy-backs
  off of the existing added onion service errors
- updates identity-icon to onionWarning.svg when visiting a v2 onion site adds
  warning tooltip; this warning supersedes all other identity states (including
  mixed-content error)
- we determine whether to show the warning page in nsDocShell::DoURILoad()
- a new synchonous IPC method is added to ContentChild/ContentParent to determine
  if the session has loaded the warning page already; worst case scenario, each
  child process will need to wait on this method to return only once when visiting
  a v2 onion; nothing is permanently cached with regards to this change
- an exception for the new sync method is added to sync-messages.ini (generally,
  in practice adding new blocking methods is probably bad, but the minimial
  overhead and frequency this method is called is worth the simpler code)

Bug 1658881 - When failing to create a channel and an image request, make sure to set the image blocking status appropriately. r=tnikkel

This is the same status as we do for known no-data protocols here:

This ensures we treat these two cases the same.

This loads HTTPS Everywhere as a builtin addon from a hardcoded
resource:// URI in desktop. It also ensures that the non-builtin
HTTPS Everywhere addon is always uninstalled on browser startup.

The reason of making this desktop-only is that there are some issues
when installing a builtin extension from geckoview side, making
the extension not available on first startup. So, at least for
now we handle the Fenix case separately. See #40118 for a followup
for investigating these.

In any case, `gCombinedSizes` should be larger than or equal to the
buffer within `MemoryClockCache`.

The `gCombinedSizes` need to be enlarged once the inner buffer within
`MemoryBlockCache` grows. Otherwise, when the `MemoryBlockCache` is
released, subtracting the buffer-size of the `MemoryBlockCache` from
`gCombinedSizes` lead to a underflow.
