target/i386: add AVX10 feature and AVX10 version property

When AVX10 enable bit is set, the 0x24 leaf will be present as "AVX10
Converged Vector ISA leaf" containing fields for the version number and
the supported vector bit lengths.

Introduce avx10-version property so that avx10 version can be controlled
by user and cpu model. Per spec, avx10 version can never be 0, the default
value of avx10-version is set to 0 to determine whether it is specified by
user.  The default can come from the device model or, for the max model,
from KVM's reported value.
