BaseTools: Fix old python2 idioms

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)
