Add sve_vl field to arch_domain and xen_arch_domainconfig struct,
to allow the domain to have an information about the SVE feature
and the number of SVE register bits that are allowed for this
domain.

allows to use less space in the st
On Arm, the SVE vector length is encoded in arch_capabilities field

field of physinfo for Arm.
Removed include for xen-tools/common-macro

This serie is introducing the possibility for Dom0 and DomU guests to use
sve/sve2 instructions.
SVE feature introduces new instruction and registers to improve performances on
floating point operations.
The SVE feature is advertised using the ID_AA64PFR0_EL1 register, SVE field, and

Save/restore context switch for SVE, allocate memory to contain
the Z0-31 registers whose length is maximum 2048 bits each and
FFR who can be maximum 256 bits, the allocated memory depends on
how many bits is the vector length for the domain and how many bits
are supported by the platform.

Add a command line parameter to allow Dom0 the use of SVE resources,
the command line parameter sve=, sub argument of dom0=,
controls the feature on this domain and sets the maximum SVE vector
length for Dom0.
Add a new function, parse_signed_integer(), to parse an integer
command line argument.
When the arm platform supports SVE, advertise the feature in the
field arch_capabilities in struct xen_sysctl_physinfo by encoding
the SVE vector length in it.
