Fix invalid UTF-8

[jeremybobbin]

Description

This patch fixes the invalid UTF-8 sequences which caused me some problems with CI(in the attempt to remove the carriage returns).

Some of the CI scripts(like the following) read the diff as UTF-8:

• .pytool\Plugin\EccCheck\EccCheck.py
• .pytool\Plugin\LicenseCheck\LicenseCheck.py

This means that if invalid UTF-8 was removed in a patch, it will raise an exception.

I do not anticipate this passing CI, however, if merged, it should prevent future CI problems.

• Breaking change?
• Impacts security?
• Includes tests?

How This Was Tested

Tested with OVMF in QEMU. I ran the affected make files to assert that there were no new parsing errors. I built antlr & dlg with no issues.

Integration Instructions

N/A

we have a plugin that checks for this automatically across files in packages.
https://github.com/tianocore/edk2/tree/master/.pytool/Plugin/CharEncodingCheck

Could that be used somehow to not only catch these issues but prevent regressions?

At first glance i think there are two issues.

1. Basetools isn't a "package". But maybe it should be somehow added to CI so that these tools can be run.
2. These files are not standard file extensions and thus may not have a rule in the CharEncodingCheck tool.

Anyway, look forward to seeing if there is a way to avoid these problems coming back.
