Re-submit the changes to enable windows pre-push checks.
This patch changes how `ci/bin/format.dart` generate diffs from `diff` and `patch` commands to `git diff` and `git apply` in order to have a common method for these operations on all platforms. Windows installations don't have diff and patch commands available by default and many implementations which provide such commands work differently than the UN*X tools. Git however works consistently across all platforms.
Additionally, this patch also changes the python executable in some of the pre-push components affected by this to `vpython3` to continue the effort started at flutter/flutter#108474 and I also removed the `--no-sound-null-safety` parameter in the ci/format.sh, ci/format.bat files
NOTE: Since the original patch caused some issues, I suggest that this should be tested more carefully before it is merged.

This converts the ci/format.sh script to a Dart script that uses process_runner and isolates to multi-process the clang-format, diffs, and grepping needed to do the formatting changes.
It also will (by default) only check the formatting of changed files.
The user can optionally check all files (--all-files) or do only some types of checks with --check. --verbose prints the versions of the tools used for Clang format and Java format.
Specifying --fix will cause any formatting errors that would have been detected to be fixed.
