target/arm: Move feature test functions to their own header

The feature test functions isar_feature_*() now take up nearly
a thousand lines in target/arm/cpu.h. This header file is included
by a lot of source files, most of which don't need these functions.
Move the feature test functions to their own header file.

+ * or where the correct answer for a CPU which doesn't implement that
+ * CPU state is "false" (eg when generating A32 or A64 code, if adding
+ * system registers that are specific to that CPU state, for "should
+ * we let this system register bit be set" tests where the 32-bit
+ * flavour of the register doesn't have the bit, and so on).
+ * Functions which simply ask "does this feature exist at all" have
+ * _any_ in their name, and always return the logical OR of the _aa64_
