fix(ios): now handles security-scoped files

fix(web): removes package namespacing from kbd's CSS class

fix(web): mobile layouts for static keyboards now %-based

fix(web): macOS 11 agent string parse

fix(windows): tsysinfox64 signature 🍒

Fixes #4484.

Cherry-pick of #4486.

chore(linux): Fix launchpad script (v13)

- We have to provide env variable to be able to select correct
  dependencies at build time
- Add focal and groovy and remove xenial and eoan
- We need to build once before creating the source package so that
  the man pages get generated. In v14 we do that during the binary
  build, but that requires additional build dependencies, so for v13
  we do it this way.

fix(linux): Don't fail installation if restarting ibus fails (v13)

If there are multiple users running `ibus-daemon` processes on the machine, we
restart ibus for all of them.

If (re-)starting ibus fails for whatever reason we should simply
ignore the failure instead of failing the entire installation/
uninstallation.

This fixes #3902.

fix(ios): tweaks to project files

fix(web): Fix layer how layer is separated from key name

chore(web): Merge remote-tracking branch 'origin/stable-13.0' into fix/web/cherry-pick/3658-fix-layer-separate

fix(windows): metro application compatibility

Fixes #3665.

On some systems, subkeys of HKCU\Software\Keyman could have incorrect
permissions and these would not be corrected with earlier fixes such as
in #2316. This fix resolves the problem by recursively correcting
permissions on all subkeys, rather than just the top two levels.

This issue caused Metro-style applications (Windows Store apps) to fail
to accept Keyman keyboard input.

This removes the requirement for the Windows 8.1 SDK.

fix(developer): Touch font size should be string 🍒

fix(windows): use new signtime.bat on build agents 🍒

Fixes #3487.

The fontsize property for touch layout elements was treated as
an integer by Developer but should be a string (as it might contain
units such as 'em').

To help with back-compat, updated the GetValue string overload
to ignore value type and return the stringified form, regardless of
the actual type, which should always work.

fix(android/engine): Dismiss notification when touched

fix(android): Fix overflow menu for hdpi devices
