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.

We can make `NodePermissions` rely on interior mutability (which the
`PermissionsContainer` is already doing) in order to not have to clone
everything all the time. This also reduces the chance of an accidental
`borrow` while `borrrow_mut`.
This commit abstracts out the specifics of the underlying system calls
FS operations behind a new `FileSystem` and `File` trait in the
`ext/fs` extension.
This allows other embedders to re-use ext/fs, but substituting in a
different FS backend.
This is likely not the final form of these traits. Eventually they will
be entirely `deno_core::Resource` agnostic, and will live in a seperate
crate.

This commit adds unstable "Deno.openKv()" API that allows to open
a key-value database at a specified path.

These methods are confusing because the arguments are backwards. I feel
like they should have never been added to `Option<T>` and that clippy
should suggest rewriting to
`map(...).unwrap_or(...)`/`map(...).unwrap_or_else(|| ...)`

This commit adds new "A" option to the interactive permission prompt, that will
allow all subsequent permissions for given group (domain). Ie. when querying for
permissions to access eg. env variables responding with "A" will allow access
to all environmental variables.
This works for all permission domains and should make permission prompts
more ergonomic for users.
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 changes permission prompt to show that "import()" API
is requesting permissions.
Given "dynamic_import.js" like so:
```
import("https://deno.land/std@0.170.0/version.ts");
```
Before:
```
deno run dynamic_import.js
⚠️ ┌ Deno requests net access to "deno.land".
├ Run again with --allow-net to bypass this prompt.
└ Allow? [y/n] (y = yes, allow; n = no, deny) >
```
After:
```
deno run dynamic_import.js
⚠️ ┌ Deno requests net access to "deno.land".
├ Requested by `import()` API
├ Run again with --allow-net to bypass this prompt.
└ Allow? [y/n] (y = yes, allow; n = no, deny) >
```
This commit refactors several things in "runtime/permissions" module:
- splits it into "mod.rs" and "prompter.rs"
- adds "PermissionPrompter" trait with two implementations:
* "TtyPrompter"
* "TestPrompter"
- adds "before" and "after" prompt callback which can be used to hide
progress bar in the CLI (to be done in a follow up)
- "permissions_prompt" API returns "PromptResponse" enum, instead
of a boolean; this allows to add "allow all"/"deny all" functionality
for the prompt
