RISC-V: testsuite: Skip tests providing -march/-mcpu for ILP32E/ILP64E ABIsHEADtrunkmaster

Some test cases explicitly set -march or -mcpu with extensions which
are not compatible with the E ABI variants.  This leads to spurious
errors when toolchain has been configured for RV32E base ISA and
ILP32E ABI:
  cc1: error: ILP32E ABI does not support the 'D' extension

Also, test gcc.target/riscv/rvv/base/pr119164.c implicitly requires
rv64 since it explicitly selects -march=rv64gcv_zvl256b:
  cc1: error: ABI requires '-march=rv32'

Testing done:
 - Ensured cross riscv64-unknown-linux-gnu has no difference in test
   output with and without the patch.
 - For riscv32-unknown-elf  there are no new failures. Test case pr119164.c
   no longer fails and is now marked as unsupported.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/mcpu-xt-c908.c: Disable for E ABI variants.
	* gcc.target/riscv/mcpu-xt-c908v.c: Ditto.

	* gcc.target/riscv/mcpu-xt-c910v2.c: Ditto.
	* gcc.target/riscv/mcpu-xt-c920.c: Ditto.
	* gcc.target/riscv/mcpu-xt-c920v2.c: Ditto.

	* gcc.target/riscv/pr120223.c: Ditto.
	* gcc.target/riscv/rvv/base/pr119164.c: Disable for E ABI variants
	and for 32-bit ISA.
