File msvcrt-common.def.in adds just symbol aliases, so include it in CRT

API for __getmainargs() and __wgetmainargs() functions in msvcrt20.dll is

the attribute.

All CRT import libraries provides UCRT-compatible *stat* symbols since
commit b4638756158e947ce3ddde9e1b3b6f1f63d2ba03.
So define all stat* macros consistently with definitions of aliases in def
files based on UCRT. There is no need to have ifdef for non-UCRT version
anymore.

For 32-bit time_t (detected by _USE_32BIT_TIME_T), functions _fstat32(),
_fstat() and fstat() are same. So fstat() can be defined as simple alias
in def file.
Same applies for functions _fstat64i32(), _fstat() and fstat() when time_t
is 64-bit.
Simplify fstat() function, remove it from mingw-w64-
API for __getmainargs() function in msvcrt10.dll is same as __GetMainArgs()

structure as a last argument.

getopt* functions receive also argv[0] argument. So use it for printing
program name instead of the global __argv[0] variable.
This avoids using and importing of the __argv[] DATA symbol from the linked
CRT library, as it is not needed.

Having -DDEF_ is required by func.def.in which is used either
directly or indirectly by crt-aliases.def.in in all CRT def.in files.
Some symbols in crt-aliases.def.in are defined via F* macros and these
symbols are currently missing in versioned non-os msvcrt import libraries.
This change is fixin
Add once-guard to ensure that the file is processed only once.
Add arch-guard to ensure that DEF_ is always defined to prevent an
issue that symbols defined via F32() macro completely disappeared and which
was fixed in previous change.
This change applied before the previous change cause compile
