ci: Add AArch64 firmware build to release workflow

Split the monolithic build job into parallel build-x64 and
build-aarch64 jobs feeding a dependent release job. Cross-compile
AArch64 using gcc-aarch64-linux-gnu with the edk2 build command
directly

Upgrade deprecated actions

Bump runner to ubuntu-24.04

Drop python3-distutils from build deps
