Fix PR ada/111909 On Darwin, determine filesystem case sensitivity at
runtime
In gcc/ada/adaint.c(__gnat_get_file_names_case_sensitive), the current
assumption for __APPLE__ is that file names are case-insensitive
unless __arm__ or __arm64__ are defined, in which case file names are
declared case-sensitive.
The associated comment is
"By default, we suppose filesystems aren't case sensitive on
Windows and Darwin (but they are on arm-darwin)."
This means that on aarch64-apple-darwin, file names are treated as
case-sensitive, which is not the default case.
The true default position is that macOS file systems are
case-insensitive, iOS file systems are case-sensitive.
Apple provide a header file which permits a
compile-time check for the compiler target (e.g. OSX vs IOS); if
TARGET_OS_IOS is defined as 1, this is a build for iOS.

(__gnat_get_file_names_case_sensitive): Split out the __APPLE__
check and remove the checks for __arm__, __arm64__. For Apple,
file names are by default case-insensitive unless TARGET_OS_IOS is
set.
