0cb5bc6707 ICU-22843 Disambiguate UnicodeString::readOnlyAlias() for MSVC. 
Both std::u16string_view and std::wstring_view are possible matches for
UnicodeString as a template parameter, but adding an explicit overload
avoids both having to make that choice and taking the detour through
creating any string view at all.

6c9d39a08c ICU-22843 Enable constructing UnicodeString from literal in fixed time. 
When passing a string literal to any of the legacy constructors that
take just a plain pointer to a UTF-16 string it becomes necessary to
iterate through the string to find its length, even though this length
was known to the compiler (which just has no way of passing it on to the
constructor).

But when calling the new templated string view constructor instead it
becomes possible for the compiler to use the known length of a string
literal to directly create a string view of the correct size and pass
this on to the constructor.

By replacing the legacy constructors with the new constructor this is
made the default behaviour.

638acd0c38 ICU-21374 Add a CFI build bot for ICU4C 
Add the github action bot to build with cfi
Also fix all the known issues which require the change from C style cast to
static_cast inside the i18n and common directory while we are sure about
the object. and use
C++ style dynamic_cast for base-to-derive cast in other code inside i18n
and common and in test code or tool.
Change to use const_cast for casting between const / non-const

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.

fd5a346b3d ICU-21778 UnicodeString::clone error handling fix 
Change UnicodeString::clone() to return a nullptr if the underlying copy
constructor produces a bogus string. This can happen if the copy constructor
encounters a memory allocation failure in allocating the copy's internal string
buffer, or if the string being copied was already bogus.

The change is consistent with other ICU clone functions, which are generally
defined to return nullptr in case of errors.
