build QEMU 10.2.2 from source in CI for mapped-ram support

Browse Source 
Ubuntu 24.04 (ubicloud-standard-8) ships QEMU 8.2, which predates the
mapped-ram migration capability used by the fast-resume snapshot path.
Compile 10.2.2 once per runner image and cache the resulting /opt/qemu
so subsequent runs are fast.
