a74a6e3ba1 n-api: run all finalizers via SetImmediate()
Throwing an exception from a finalizer can cause the following fatal
error:

Error: async hook stack has become corrupted (actual: 2, expected: 0)
 1: 0x970b5a node::InternalCallbackScope::~InternalCallbackScope()
    [./node]
 2: 0x99dda0 node::Environment::RunTimers(uv_timer_s*) [./node]
 3: 0x13d8b22  [./node]
 4: 0x13dbe42 uv_run [./node]
 5: 0xa57974 node::NodeMainInstance::Run() [./node]
 6: 0x9dbc17 node::Start(int, char**) [./node]
 7: 0x7f4965417f43 __libc_start_main [/lib64/libc.so.6]
 8: 0x96f4ae _start [./node]

By https://github.com/nodejs/node/issues/34341#issuecomment-658426281,
calling into JS from a finalizer and/or throwing exceptions from there
is not advised, because the stack may or may not be set up for JS
execution. The best solution is to run the user's finalizer from a
`SetImmediate()` callback.

test: refactor common.expectsError
This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.

The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.

This has the side effect that `common` is used significantly less
frequent.

938e11882b test: partition N-API tests
Partition test/addons-napi into test/js-native-api and test/node-api to
isolate the Node.js-agnostic portion of the N-API tests from the
Node.js-specific portion.
