Previously we had two encodings for JS files:
1. If a file contains only ASCII characters, encode it as a one-byte
string (interpreted as uint8_t array during loading).
2. If a file contains any characters with code point above 127,
encode it as a two-byte string (interpreted as uint16_t array
during loading).
This was done because V8 only supports Latin-1 and UTF16 encoding
as underlying representation for strings. To store the JS code
as external strings to save encoding cost and memory overhead
we need to follow the representations supported by V8.
Notice that there is a gap in the Latin1 range (128-255) that we
encoded as two-byte, which was an undocumented TODO for a long
time. That was fine previously because then files that contained
code points beyond the 0-127 range contained code points >255.
Now we have undici which contains code points in the range 0-255
(minus a replaceable code point >255). So this patch adds handling
for the 128-255 range to reduce the size overhead caused by encoding
them as two-byte. This could reduce the size of the binary by
~500KB and helps future files with this kind of code points.
Drive-by: replace `’` with `'` in undici.js to make it a Latin-1
only string. That could be removed if undici updates itself to
replace this character in the comment.

This patch adds support for using
`vm.constants.USE_MAIN_CONTEXT_DEFAULT_LOADER` as
`importModuleDynamically` in all APIs that take the option
except `vm.SourceTextModule`. This allows users to have a shortcut
to support dynamic import() in the compiled code without missing
the compilation cache if they don't need customization of the
loading process. We emit an experimental warning when the
`import()` is actually handled by the default loader through
this option instead of requiring `--experimental-vm-modules`.
In addition this refactors the documentation for
`importModuleDynamically` and adds a dedicated section for it
with examples.
`vm.SourceTextModule` is not supported in this patch because
it needs additional refactoring to handle `initializeImportMeta`,
which can be done in a follow-up.

We define a new type called `node_api_nogc_env` as the `const` version
of `napi_env` and `node_api_nogc_finalize` as a variant of
`napi_finalize` that accepts a `node_api_nogc_env` as its first
argument.
We then modify those APIs which do not affect GC state as accepting a
`node_api_nogc_env`. APIs accepting finalizer callbacks are modified to
accept `node_api_nogc_finalize` callbacks. Thus, the only way to attach
a `napi_finalize` callback, wherein Node-APIs affecting GC state may be
called is to call `node_api_post_finalizer` from a
`node_api_nogc_finalize` callback.
In keeping with the process of introducing new Node-APIs, this feature
is guarded by `NAPI_EXPERIMENTAL`. Since this feature modifies APIs
already marked as stable, it is additionally guared by
`NODE_API_EXPERIMENTAL_NOGC_ENV`, so as to provide a further buffer to
adoption. Nevertheless, both guards must be removed upon releasing a
new version of Node-API.
