BaseTools/Scripts/PatchCheck: Error if commit modifies multiple packages

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4679

Update PatchCheck.py to evaluate all the files modified in each commit
and generate an error if:
* A commit adds/modifies files in multiple package directories
* A commit adds/modifies files in multiple non-package directories
* A commit adds/modifies files in both a package and a non-package
  directory
* A commit deletes files from multiple package directories
* A commit deletes files from multiple non-package directories
* A commit deletes files from both a package and a non-package
  directory

Modifications to files in the root of the repository are not
evaluated.

This check is skipped if PatchCheck.py is run on a patch file or
input from stdin because this multiple package commit check depends
on information from a git repository.

If --ignore-multi-package option is set, then reduce the multiple
package commit check from an error to a warning for all commits in
the commit range provided to PatchCheck.py.

Add check for a 'Continuous-integration-options:' commit message
tag that allows one or more options to be specified at the individual
commit scope to enable/disable continuous integration checks. This
tag must start at the beginning of a commit message line and may
appear more than once in a commit message.

Add support for a Continuous-integration-options tag value of
'PatchCheck.ignore-multi-package' that reduces the multiple package
commit check from an error to a warning for the specific commits that
specify this option.  Example:

  Continuous-integration-options: PatchCheck.ignore-multi-package

The set of packages are found by searching for DEC files in a git
repository. The list of DEC files in a git repository is collected
with the following git command:

  git ls-files *.dec

The set of files added/modified by each commit is found using the
following git command:

  git diff-tree --no-commit-id --name-only --diff-filter=AM -r <commit>

The set of files deleted by each commit is found using the
following git command:

  git diff-tree --no-commit-id --name-only --diff-filter=D -r <commit>
