chore(core): enable debuglink compilation on touch models

What changed, and why it matters
This commit only changes build configuration files for Trezor hardware wallets. It adds the debug touch and button source files to the compilation when a debug USB interface is requested. There is no change to runtime behavior, user-facing functionality, or security logic. It is a build-system chore.
Recommended action
No security action required. Review as normal build maintenance if relevant to release engineering.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit modifies SCons model files for T2T1, T3T1, and T3W1 variants (emulator and hardware) to include embed/io/touch/touch_debug.c and, for T3W1 revA/revB, embed/io/button/button_debug.c when usb_iface_debug is in features_wanted. This is purely enabling compilation of existing debug code under the existing debug feature flag. No source code logic is changed.
