tests: increase CI integration test parallelism

Browse Source 
Increase the number of parallel integration tests in CI to save ~3-5
minutes per x86_64 run. The thread limit is driven by RAM and disk
space constraints, not CPU availability.

A new `PARALLEL_INTEGRATION_TESTS_NUM` environment variable controls
the thread count. In CI it is set explicitly (12 for x86_64, 25 for
ARM64); locally it falls back to `nproc / 4`, preserving the previous
behavior.

Only the first test group (`common_parallel`, `live_migration_parallel`)
uses the overridden value - subsequent groups (dbus_api, fw_cfg,
ivshmem, aarch64_acpi) continue to use the `nproc / 4` default.
