Fix handling of am/pm indicators in mapping from CLDR to Qt formats

Both qlocale_mac.mm and dateconverter.py were mapping the CLDR am/pm
indicator, 'a', to the Qt format token 'AP', forcing the indicator to
uppercase. The LDML spec [0] says:

    May be upper or lowercase depending on the locale and other
    options.

We don't support the "other options" mentioned, but we can at least
(since 6.3) preserve the the locale-appropriate case, instead of
forcing upper-case. As such, this change is a follow-up to
commit 4641ff0f6a1b0da6f55db5e33c58a77be2032808

Changes locale data, as expected, to use "Ap" in place of "AP" in
various formats in the time_format_data[] array.

[ChangeLog][QtCore][QLocale] Where CLDR specifies an am/pm indicator,
the case of the CLDR-supplied indicator is used, where previously
QLocale forced it to upper-case.
