Yifan Liu 5c9456462b hv && config-tool: Add compilation option to disable all interrupts in HV 
This patch adds an option CONFIG_KEEP_IRQ_DISABLED to hv (default n) and
config-tool so that when this option is 'y', all interrupts in hv root
mode will be permanently disabled.

With this option to be 'y', all interrupts received in root mode will be
handled in external interrupt vmexit after next VM entry. The postpone
latency is negligible. This new configuration is a requirement from x86
TEE's secure/non-secure interrupt flow support. Many race conditions can be
avoided when keeping IRQ off.

v5:
Rename CONFIG_ACRN_KEEP_IRQ_DISABLED to CONFIG_KEEP_IRQ_DISABLED

v4:
Change CPU_IRQ_ENABLE/DISABLE to
CPU_IRQ_ENABLE_ON_CONFIG/DISABLE_ON_CONFIG and guard them using
CONFIG_ACRN_KEEP_IRQ_DISABLED

v3:
CONFIG_ACRN_DISABLE_INTERRUPT -> CONFIG_ACRN_KEEP_IRQ_DISABLED
