testsuite: RISC-V: Add effective target for E ABI variant
Add new effective target check for either ILP32E or ILP64E ABI variants.
Initial implementation only checks for RV32E or RV64E ISA, which in turn
implies that ILP32E/ILP64E ABI is used. The RV32I+ILP32E and
RV64I+ILP64E combinations are not yet caught by the check, but they
do not seem to be widely used currently.
gcc/testsuite/ChangeLog:
* lib/target-supports.exp (check_effective_target_riscv_abi_e):
New procedure.
