In Python 3.12 invalid escape sequences in strings moved from
DeprecationWarning to SyntaxWarning
(ref https://docs.python.org/3/whatsnew/changelog.html#python-3-12-0-final
and search for gh-98401). In a future Python version this will become
SyntaxError.
Multiple instances of these SyntaxWarnings are currently printed when
running the BaseTools tests using Python 3.12 (though without actually
failing the affected tests).
This commit updates all lines which were causing this type of warning.
Typical examples which needed fixing are:
- "BaseTools\Source\Python" representing a path: "\S" and "\P" are invalid
escape sequences, therefore left unchanged, therefore the test works
(with a warning in Python 3.12). r"BaseTools\Source\Python" represents
the same string, but with escapes turned off completely thus no warning.
- Where '\t\s' is used as a regex pattern, then chr(9) + '\\s' is sent
to the regex parser (with a warning in Python 3.12) since '\s' is not a
valid Python escape sequence. This works correctly, though arguably for
the wrong reasons. r'\t\s' sends the same as '\\t\\s', as originally
intended and with no warning.
(Note that ' and " are not fundamentally different in Python.)

This reverts commit 6693f359b3c213513c5096a06c6f67244a44dc52..
678f85131238622e576705117e299d81cff755c9.
Python3 migration is the fundamental change. It requires every developer
to install Python3. Before this migration, the well communication and wide
verification must be done. But now, most people is not aware of this change,
and not try it. So, Python3 migration is reverted and be moved to edk2-staging
Python3 branch for the edk2 user evaluation.

Based on "futurize -f lib2to3.fixes.fix_idioms"
* Change some type comparisons to isinstance() calls:
type(x) == T -> isinstance(x, T)
type(x) is T -> isinstance(x, T)
type(x) != T -> not isinstance(x, T)
type(x) is not T -> not isinstance(x, T)
* Change "while 1:" into "while True:".
* Change both
v = list(EXPR)
v.sort()
foo(v)
and the more general
v = EXPR
v.sort()
foo(v)
into
v = sorted(EXPR)
foo(v)

For case-insensitive file systems, edk2 String.py collides with the
Python string.py, which results in build errors. This,for example,
applies to building via the Windows Subsystem for Linux from a
DriveFS file system. This patch renames String to StringUtils to
prevent conflicts for case-insensitive file systems.
