fix(windows): Keyman crash and interop with Metro-style apps 🍒

cherry(web): Fixes mnemonic code handling issues

cherry(web): iOS-Safari user agent spoof detection

cherry(web): Bounds-check on context deletion from keyboard rules

Fixes #1680. This issue arose only on some systems where
permissions for Keyman registry keys were not being
set correctly.

Fixes #2147.

This potentially addresses the issues reported in #2147 where Keyman
would crash due to a race condition as a critical section was not
deleted before attempting to recreate it.

Some logging has been added for debugging these issues.

Also fixes memory leaks and another race on startup relating to loading
the taskbar icon.

There are still some known memory leaks because DLL_THREAD_DETACH is
not called for all threads before keyman32.dll is unloaded, so those
threads don't get the opportunity to clean themsselves up. However, the
key danger with the csGlobals critical section has been addressed.

cherry(iOS):  Toolchain update

fix: Temporarily disable dictionary when entering password field

Per review comment, separate getter and setter of state variable.
