mimalloc3 wasi target fails to compile

I get the compilation errors when I try to build mimalloc3 using wasi target.

git clone --branch v3.1.5 https://github.com/microsoft/mimalloc.git

I'm able to get rid of those by s/mi_align_up_ptr/_mi_align_up_ptr. I'm happy to create PR if that's what needed to fix it.

Same issue here building from the 3.0.10 tag. I've just added -Dmi_align_up_ptr=_mi_align_up_ptr to work around it.
