testsuite: arm: Use -march=unset for bfloat16_scalar* tests

Update test cases to use -mcpu=unset/-march=unset feature introduced in
r15-3606-g7d6c6a0d15c.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/bfloat16_scalar_1_1.c: Use effective-target
	arm_arch_v8_2a_bf16_hard.
	* gcc.target/arm/bfloat16_scalar_2_1.c: Likewise.
	* gcc.target/arm/bfloat16_scalar_3_1.c: Likewise.
	* gcc.target/arm/bfloat16_scalar_1_2.c: Use effective-target
	arm_arch_v8_2a_bf16.
	* gcc.target/arm/bfloat16_scalar_2_2.c: Likewise.
	* gcc.target/arm/bfloat16_scalar_3_2.c: Likewise.
	* lib/target-supports.exp: Define effective-target
	v8_2a_bf16 and v8_2a_bf16_hard.
