This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This commit changes the build process in a way that preserves already
registered ops in the snapshot. This allows us to skip creating hundreds of
"v8::String" on each startup, but sadly there is still some op registration
going on startup (however we're registering 49 ops instead of >200 ops).
This situation could be further improved, by moving some of the ops
from "runtime/" to a separate extension crates.

This implements two macros to simplify extension registration and centralize a lot of the boilerplate as a base for future improvements:
* `deno_core::ops!` registers a block of `#[op]`s, optionally with type
parameters, useful for places where we share lists of ops
* `deno_core::extension!` is used to register an extension, and creates
two methods that can be used at runtime/snapshot generation time:
`init_ops` and `init_ops_and_esm`.

Turns out we were cloning permissions which after prompting were discarded,
so the state of permissions was never preserved. To handle that we need to store
all permissions behind "Arc<Mutex<>>" (because there are situations where we
need to send them to other thread).
Testing and benching code still uses "Permissions" in most places - it's undesirable
to share the same permission set between various test/bench files - otherwise
granting or revoking permissions in one file would influence behavior of other test
files.
This commit removes implementation of "native plugins" and replaces
it with FFI API.
Effectively "Deno.openPlugin" API was replaced with "Deno.dlopen" API.
This commit adds allowlist support to `--allow-run` flag.
Additionally `Deno.permissions.query()` allows to query for specific
programs within allowlist.
Allowlist checking already uses hosts but for some reason
requests, revokes and the runtime permissions API use URLs.
- BREAKING(lib.deno.unstable.d.ts): Change
NetPermissionDescriptor::url to NetPermissionDescriptor::host
- fix(runtime/permissions): Don't add whole URLs to the
allowlist on request
- fix(runtime/permissions): Harden strength semantics:
({ name: "net", host: "127.0.0.1" } is stronger than
{ name: "net", host: "127.0.0.1:8000" }) for blocklisting
- refactor(runtime/permissions): Use tuples for hosts, make
the host optional in Permissions::{query_net, request_net, revoke_net}()
This commit moves Deno JS runtime, ops, permissions and
inspector implementation to new "deno_runtime" crate located
in "runtime/" directory.
Details in "runtime/README.md".
