The function follows various libc functions in forcing the caller to decide the case of the exponent separator, rather than allowing them to opt for the case the locale normally uses. At Qt 6 I changed the code reading from CLDR to not force the case, but didn't change toString() to force lower when that was requested. Since the function is documented to use lower-case when that's what it asks for, change it to do what it says in its documentation. A caller who wants the locale-appropriate case is thus obliged to call exponential() and scan it for lower- or upper-case letters and select the right one of 'e' and 'E' (or 'g' and 'G') to match. This partially reverts some test changes made in commit d5bb8d5150498dc059e8c17f224c66fb1a6bcf32 and expands the QLocale tests to include ones matching those it changed. Fixed some tests of QDoubleValidator that previously turned 'e' in the input into 'E' in the output; roughly alternate between changing the input to match the output and the other way round, to be sure we exercise both branches of the test.
