{:d} format should support bool value.

[xiaxinmeng]

{:d} format is supported to pass a boolean value. See the following test case. CPython can execute it and return expected result, while RustPython report a TypeError.

for i in range(12):
    print('{:d}, '.format(chr(i) in "ss"), end='')
    if i % 16 == 1:
        print()

Behaviors on CPython:

0, 0, 
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 

Behaviors on RustPython

Traceback (most recent call last):
  File "/home/xxm/Desktop/RustPython/test.py", line 169, in <module>
    print('{:d}, '.format(chr(i) in "ss"), end='')
TypeError: unsupported format string passed to bool.__format__

@JazzGlobal are you interested in trying this one out? I think it's similar to what you contributed recently.

Sure I can take it!

Since #4948 only covered :d, we should probably make additional issues to cover the other FormatType options. They would probably be good first issues as well.

Thanks! I have included additional test cases in order to address the formatting issue in #4950. I hope these new cases will be helpful in resolving the format issue

Thank you!
