Ake Koomsin 33cc88261c target/i386: add support for VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE 
Current QEMU can expose waitpkg to guests when it is available. However,
VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE is still not recognized and
masked by QEMU. This can lead to an unexpected situation when a L1
hypervisor wants to expose waitpkg to a L2 guest. The L1 hypervisor can
assume that VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE exists as waitpkg is
available. The L1 hypervisor then can accidentally expose waitpkg to the
L2 guest. This will cause invalid opcode exception in the L2 guest when
it executes waitpkg related instructions.

This patch adds VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE support, and
sets up dependency between the bit and CPUID_7_0_ECX_WAITPKG. QEMU should
not expose waitpkg feature if VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE is
not available to avoid unexpected invalid opcode exception in L2 guests.

/***** Steps involved on loading and filtering CPUID data
*
* When initializing and realizing a CPU object, the steps
* involved in setting up CPUID data are:
*
* 1) Loading CPU model definition (X86CPUDefinition). This is
* implemented by x86_cpu_load_model() and should be completely
* transparent, as it is done automatically by instance_init.
* No code should need to look at X86CPUDefinition structs
* outside instance_init.
*
* 2) CPU expansion. This is done by realize before CPUID
* filtering, and will make sure host/accelerator data is
* loaded for CPU models that depend on host capabilities
* (e.g. "host"). Done by x86_cpu_expand_features().
*
* 3) CPUID filtering. This initializes extra data related to
* CPUID, and checks if the host supports all capabilities
* required by the CPU. Runnability of a CPU model is
* determined at this step. Done by x86_cpu_filter_features().
*
* Some operations don't require all steps to be performed.
* More precisely:
*
* - CPU instance creation (instance_init) will run only CPU
* model loading. CPU expansion can't run at instance_init-time
* because host/accelerator data may be not available yet.
* - CPU realization will perform both CPU model expansion and CPUID
* filtering, and return an error in case one of them fails.
* - query-cpu-definitions needs to run all 3 steps. It needs
* to run CPUID filtering, as the 'unavailable-features'
* field is set based on the filtering results.
* - The query-cpu-model-expansion QMP command only needs to run
* CPU model loading and CPU expansion. It should not filter
* any CPUID data based on host capabilities.
