chore(linux): Update debian changelog

chore: Add #7554 to HISTORY.md

auto: increment stable-15.0 version to 15.0.273

Merge pull request #7538 from keymanapp/fix/developer/cherry-pick/7529-enforce-us-layout-for-debugger

fix(developer): Use US base layout for debugger 🍒

fix(ios): iPad was not recognised as tablet device 🍒

Fixes #7517.

Cleans up the setDeviceType code which was attempting to set the device
type far too late in the init sequence, and moves responsibility for
detection from kmwembedded.ts to ios-host.ts, as this device test is
iOS-specific.

fix(android/engine): Dismiss key previews and subkeys on multi-touch 🍒

fix(android/engine): Dismiss subkeys when hiding keyboard 🍒

fix(developer): handle LControl being set by Windows when AltGr pressed 🍒

fix(android/engine): Dismiss subkeys on multi-touch

Fixes #7529.

We must always use the US base layout for the debugger, as positional
keyboards are not affected by the active Windows system keyboard. This
fix ensures that the behaviour in the debugger matches what the user
experiences in Keyman for Windows.

Note that this does not address support for mnemonic layouts, tracked in
issue #1074.

Fixes #7506.

In the keyboard debugger, we need to mask out LControl when AltGr is
pressed by the user, because Windows will generate LControl + AltGr for
European layouts.

Note: have also hidden the System Keyboard debug setting in this commit,
given it is not currently implemented; see #1225.

A follow-up issue is #7529.
