Replace the --enable-git-update and --disable-git-update configure params with the param --with-git-submodules=(update|validate|ignore) to allow 3 options for building from a git repo. This is needed because downstream packagers, e.g. Debian, Ubuntu, etc, also keep the source code in git, but do not want to enable the 'git_update' mode; with the current code, that's not possible even if the downstream package specifies --disable-git-update. The previous parameters are deprecated but still available; the --enable-git-update parameter maps to --with-git-submodules=update and --disable-git-update parameter maps to --with-git-submodules=validate. The configure script behavior is slightly modified, where previously the dtc, capstone, and slirp submodules were not validated when --disable-git-update was specified (but were updated with git-update enabled), now they are validated when using --with-git-submodules=validate and are only ignored when using --with-git-submodules=ignore.
