Add missing functions from thumb arch

[kr-t]

Target hardware: https://www.st.com/en/evaluation-tools/b-u585i-iot02a.html
(cortex-m33, thumbv8m.main, eabihf)
When running it in Zephyr with AoT enabled, without my changes, it raises following error:
AOT module load failed: resolve symbol __aeabi_memmove failed

After adding these functions, runtime can pass this check and normally load the application.

@kr-t could you share the full aot compilation flags?

I have following in my app:
*((volatile uint32_t *)(uintptr_t)(0xFFFFD000UL + 0x1C00UL + 0x18UL)) = (uint32_t)(1u << 1);

Build commands:

• clang: /opt/wasi-sdk/share/cmake/../..//bin/clang --target=wasm32-wasi -Wl,--strip-all -Wl,--allow-undefined "CMakeFiles/hello-world.wasm.dir/main.c.obj" -o hello-world.wasm
• wamrc: wamrc --cpu=cortex-m33 --target=thumbv8m.main --target-abi=eabihf --enable-shared-heap -o hello-world.aot hello-world.wasm

Without this PR:
AOT module load failed: resolve symbol __aeabi_memmove failed

With this PR:
My application starts
