x86: Move CPU_FEATURE{S}_{USABLE|ARCH}_P to isa-level.h

Move X86_ISA_CPU_FEATURE_USABLE_P and X86_ISA_CPU_FEATURES_ARCH_P to
where MINIMUM_X86_ISA_LEVEL and XXX_X86_ISA_LEVEL are defined.

+/* Both X86_ISA_CPU_FEATURE_USABLE_P and X86_ISA_CPU_FEATURES_ARCH_P
+   macros are wrappers for the respective CPU_FEATURE{S}_{USABLE|ARCH}_P
+   runtime checks.  They differ in two ways.
+
+    1.  The USABLE_P version is evaluated to true when the feature
+        is enabled.
+
+    2.  The ARCH_P version has a third argument `not`.  The `not`
+        argument can either be `!` or empty.  If the feature is
+        enabled above an ISA level, the third argument should be empty
+        and the expression is evaluated to true when the feature is
+        enabled.  If the feature is disabled above an ISA level, the
+        third argument should be `!` and the expression is evaluated
+        to true when the feature is disabled.
