nodejs: support cross compile without qemu user conditionally

Due to the scope of supported BSPs by qemu-user is limited, such
as a segment fault on armv9 after qemu apply commit [target/arm:
Convert LDAPR/STLR (imm) to decodetree][1]
```
|tmp-glibc/work/neoversen2-crypto-wrs-linux/nodejs/20.5.1/node-v20.5.1/out/
Release/v8-qemu-wrapper.sh: line 7: 3179613 Segmentation fault      (core dumped)
PSEUDO_UNLOAD=1 qemu-aarch64 -r 5.15 -L tmp-glibc/work/neoversen2-crypto-wrs-linux/

```

Upstream nodejs have cross compile support, but it needs host and target
have same bit width (e.g. a x86_64 host targeting arrch64 to produce a
64-bit binary). So:
1. If host and target have different bit width, build with QEMU user as usual;

2. If host and target have same bit width, enable notejs cross compile support:
- The build tools of nodejs is GYP[2], set CC_host, CFLAGS_host,
  CXX_host, CXXFLAGS_host, LDFLAGS_host, AR_host for host build
  which is separated with target build [3]
- Satisfy layer compatibility, set GYP variables in prefuncs of do_configure,
  do_compile and do_install other than in recipe parsing
- Add missing native packages to fix library missing on host build
- Rework libatomic.patch, explicitly link to libatomic for clang
  conditionally
