PR #7449 added modifier event to make ensure modifer events
where sent to the serializer even if the key stroke was determined
the key stroke did not need seralizing. However, a logic error was made
trying to use the exiting 'Flag' however this was not set in the
!UseCachedHotkeyModifierState case. This change adds helper function
to simply check if the key is a modifier key and send it to the
event seralizer in that case. Separating from the other logic which
is more concerned with handling hotkeys.

fix(windows): shutdown fix masked modal result 🔥 🍒

fix(windows): shutdown fix masked modal result 🔥

Regression introduced in #7661 (17.0 alpha), #7825 (16.0 beta).

When shutting down CEF cleanly, we needed to pause the form destruction
sequence in order for CEF to complete its shutdown tasks. However, for
a dialog form, it will commonly be closed by setting `ModalResult` to a
non-zero value. In our fix, we inadvertently lost any `ModalResult`
value by calling `Close` after CEF was finished, which sets
`ModalResult` to `mrCancel` (value of 2).

This fix caches the `ModalResult` value, and if non-zero, uses it
instead after CEF shuts down, to achieve the same result.

chore: Revert "chore(common): Fix shellcheck warnings"

Fixes #7926.

Android 5.0 (Chrome 37) only supports ES3. Thus, we should transpile our
lexical models to ES3 rather than ES2015, for now at least.

For example, this forces constructs such as `const` to be replaced with
`var`.
