ARM32 build is broken after JDK-8301997

Commit ffa35d8cf181cfbcb54497e997dbd18a9b62b97 removed class ConstantPoolCacheEntry which is still referenced by `src/hotspot/cpu/arm/interp_masm_arm.cpp`.

This breaks ARM32 build with the following error:
-----------
/<<PKGBUILDDIR>>/src/hotspot/cpu/arm/interp_masm_arm.cpp: In member function 'void InterpreterMacroAssembler::get_cache_and_index_and_bytecode_at_bcp(Register, Register, Register, int, int, size_t)':
/<<PKGBUILDDIR>>/src/hotspot/cpu/arm/interp_masm_arm.cpp:245:96: error: 'ConstantPoolCacheEntry' was not declared in this scope; did you mean 'ConstantPoolCache'?
  245 | ldrb(bytecode, Address(bytecode, (1 + byte_no) + in_bytes(ConstantPoolCache::base_offset() + ConstantPoolCacheEntry::indices_offset())));
