ci: install TriCore QEMU for AURIX CI builds

Add pre-built qemu-system-tricore from the qemu-tricore mirror
to enable twister test runs for the Infineon AURIX TriCore
architecture targets (qemu_tc3x, qemu_tc4x).

Supports the following machine models:
- KIT_AURIX_TC277_TRB (TC1.6P / TC3xx)
- KIT_AURIX_TC397B_TRB (TC1.6P / TC3xx)
- KIT_A3G_TC4D7_LITE (TC1.8P / TC4xx)

Runtime dependency libpixman-1-0 is needed as the binary is
dynamically linked. libglib2.0-0 is already available in the
base image.

x86_64 only as no ARM64 build is available.
