  Log Message:
  -----------
  Drop Watcom C compiler support.

The only Watcom-specific code in the tree was a <tchar.h> _vsntprintf
mapping in crypto/cryptlib.c. There is no Watcom entry in Configurations/,
no CI job builds with Watcom, and the tree has had no other Watcom-aware
code in many years. The _vsntprintf symbol is supplied by <tchar.h>
on every supported Windows toolchain (MSVC, MinGW), so the conditional
fallback is dead.

  We no longer need to test for GCC versions this old

The minimum gcc to compile our code appears to be version 9, and
we are now C99.

All these older checks become a tautology on anything that will
build a modern OpenSSL tree, so clean this up.

  Log Message:

  Simplify printf-attribute guards in bio.h.in and test/testutil/output.h.

Now that C99 is the base level, and we are no longer supporting old
GCC's, The ossl_bio__printf__ / ossl_test__printf__ indirection only existed
to pick the gnu_printf attribute over the printf attribute for MinGW's MS-CRT printf, but
MinGW is already excluded by the outer guard, so we can use the modern attribute
everywhere this code runs.
