macos: yet another tbd adjustment

Browse source 
configure:
- re-enable apple M1-arm64
- however, with --cpu=x86_64,  set -arch in CFLAGS/LDFLAGS too
  (assume rosetta)

Makefile:
- re-enable osx cross-test (Please do not disable tests)

tcc.h
- set TCC_IS_NATIVE for TCC_TARGET_MACHO on __APPLE__
- apply TCC_USING_DOUBLE_FOR_LDOUBLE for x86_64-osx

libtcc.c:
- cleanup tcc_add_file_internal()
- new function char *tcc_load_text(int fd); and use it for tbd files
