RISC-V: Add test cases for avg_ceil vaadd implementation

Add asm and run testcase for avg_ceil vaadd implementation.

The below test suites are passed for this patch series.
* The rv64gcv fully regression test.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/avg.h: Add test helper macros.
	* gcc.target/riscv/rvv/autovec/avg_data.h: Add test data for
	avg_ceil.
	* gcc.target/riscv/rvv/autovec/avg_ceil-1-i16-from-i32.c: New test.
	* gcc.target/riscv/rvv/autovec/avg_ceil-1-i16-from-i64.c: New test.
	* gcc.target/riscv/rvv/autovec/avg_ceil-1-i32-from-i64.c: New test.
