Fixes #19568
Values are not coerced to the desired type during deserialisation. This
makes serde_v8 stricter.

`ZeroCopyBuf` was convenient to use, but sometimes it did hide details
that some copies were necessary in certain cases. Also it made it way to easy
for the caller to pass around and convert into different values. This commit
splits `ZeroCopyBuf` into `JsBuffer` (an array buffer coming from V8) and
`ToJsBuffer` (a Rust buffer that will be converted into a V8 array buffer).
As a result some magical conversions were removed (they were never used)
limiting the API surface and preparing for changes in #19534.
This commit adds unstable "Deno.openKv()" API that allows to open
a key-value database at a specified path.

This commit fixes one ocurrence of unsoundness by using the newly added
API (`v8::String::write_utf8_uninit`).
See also
[`clippy:uninit_vec`](https://rust-lang.github.io/rust-clippy/master/index.html#uninit_vec).
Note that it is not actually a bug. Avoiding unsoundness improves our
code quality.
Existing implementation builds an intermediate vector of object keys
when deserializing using `MapObjectAccess`.
This logic is already handled by `SeqAccess` which can be used directly
by `MapObjectAccess`.
