riscv64: Implement JNI compiler for @CriticalNative.

Implement all JNI macro assembler functions needed by the
JNI compiler to compile stubs for @CriticalNative methods.
Enable most JNI compiler tests for @CriticalNative methods
and document the reasons for keeping the remaining few tests
disabled.

Change `Riscv64Assembler::AddConst*` to store intermediate
results in `TMP` to avoid unaligned SP in the middle of a
macro operation.

Test: m test-art-host-gtest
Test: run-gtests.sh
Bug: 283082089
