This commit introduces conditional SVE (Scalable Vector Extension)
configuration options in various Yocto meta-kronos files. The condition
is based on the value of the 'SVE_DISABLE_FLAG' variable, which, when
set to '1', disables SVE features.

Changes made in this commit:
- In 'conf/multiconfig/domu.conf', the 'TUNE_CCARGS_MARCH_OPTS'
  variable is updated to include '+sve' only when 'SVE_DISABLE_FLAG'
  is not set.
- In 'recipes-core/domu-package/domu-envs.inc', the 'DOMU1_SVE' and
  'DOMU2_SVE' variables are updated to include SVE settings only when
  'SVE_DISABLE_FLAG' is not set.
- In 'recipes-extended/xen-cfg/xen-cfg.bb', the
  'EXTRA_XEN_CMDLINE_CONFIG' variable is updated to conditionally
  include 'dom0=sve=128' based on the value of 'SVE_DISABLE_FLAG'.
- In 'yocto/kas/base.yml', Introduced SVE_DISABLE_FLAG variable
- In 'classes/fvp_rd_kronos_image_features.bbclass', the TEST_SUITES is
  updated to include sve test suit only when 'SVE_DISABLE_FLAG'
  is not set.
