030fa1a479 ICU-21148 Consistently use standard lowercase true/false everywhere. 
This is the normal standard way in C, C++ as well as Java and there's no
longer any reason for ICU to be different. The various internal macros
providing custom boolean constants can all be deleted and code as well
as documentation can be updated to use lowercase true/false everywhere.

85705f04e0 ICU-21960 C++20 Warnings from ATOMIC_VAR_INIT 
Remove the ICU macros ATOMIC_INT32_T_INITIALIZER and U_INITONCE_INITIALIZER,
which made use of C++ ATOMIC_VAR_INIT, which has been removed from C++20.

With modern C++ features being available, these macros no longer served
any real need.

35dfdf1d02 ICU-21043 Fix calendar problems 
This PR fixes
ICU-21043 Erroneous date display in indian calendar of all dates prior to 0001-01-01.
ICU-21044 Hebrew Calendar calculation is incorrect when the year < 1
ICU-21045 Erroneous date display in islamic and islamic-rgsa calendars of all dates prior to 0622-07-18.
ICU-21046 Erroneous date display in islamic-umalqura calendar of all dates prior to  -195366-07-23.

The problem in the indiancal.cpp is
* ICU-21043 the gregorian/julain convesion is wrong. Swith to use
i18n/gregoimp.h fix the problem.

The problem in the hebrwcal.cpp is
* ICU-21044 Use ClockMath::floorDivid to replace x / y for x maybe <  0
also need to fix incorrect value in test file

The problem in the islamcal.cpp:
* ICU-21045: The math of % negative number for year and month is wrong.
* ICU-21046: Not use int64_t methods and caused int32_t overflow while the year is a
huge negative number. Cast to int64_t to force using the int64_t version
for the math fix the problem.

Also add tests to exhaust test 8000 years for all calendar. In quick
mode, only test 2.5 years.

Switch to 0-based month. fix TZ for test.
