Issue #14744 : Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args)
...
* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
avoids a temporary buffer in most cases.
* Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
keep a reference to the string if the output is only composed of one string
* Disable overallocation when formatting the last argument of str%args and
str.format(args)
* Overallocation allocates at least 100 characters: add min_length attribute
to the _PyUnicodeWriter structure
* Add new private functions: _PyUnicode_FastCopyCharacters(),
_PyUnicode_FastFill() and _PyUnicode_FromASCII()
The speed up is around 20% in average.

* formatfloat() uses unicode_fromascii() instead of PyUnicode_DecodeASCII()

a character: if avoids a call to ucs4lib_find_max_char() to compute
the maximum character (whereas we already know it, it is just the character
itself)
