arm64: Define CPACR_EL1_FPEN similarly to other floating point controls
The base floating point, SVE and SME all have enable controls for EL0 and
EL1 in CPACR_EL1 which have a similar layout and function. Currently the
basic floating point enable FPEN is defined differently to the SVE control,
specified as a single define in kvm_arm.h rather than in sysreg.h. Move the
define to sysreg.h and provide separate EL0 and EL1 control bits so code
managing the different floating point enables can look consistent.
