Cleanup some macro definitions in PAL

[huoyaoyuan]

Remove unused and unify multiple definitions to minipal/utils.h.

[huoyaoyuan]

The failure is because mono redefines assert and doesn't use #undef to handle conflict:

runtime/src/mono/mono/utils/dlmalloc.c

Lines 1172 to 1180 in d3ffc5f

	#ifdef DEBUG
	#if ABORT_ON_ASSERT_FAILURE
	#define assert(x) if(!(x)) ABORT
	#else /* ABORT_ON_ASSERT_FAILURE */
	#include <assert.h>
	#endif /* ABORT_ON_ASSERT_FAILURE */
	#else /* DEBUG */
	#define assert(x)
	#endif /* DEBUG */
