fix(compat): cjs/esm interop for dynamic imports (#13792)
This commit fixes CJS/ESM interop in compat mode for dynamically
imported modules.

"ProcState::prepare_module_load" was changed to accept a list
of "graph roots" without associated "module kind". That module kind
was always hardcoded to "ESM" which is not true for CJS/ESM interop -
a CommonJs module might be imported using "import()" function. In
such case the root of the graph should have "CommonJs" module kind
instead of "ESM".

feat(compat): CJS/ESM interoperability (#13553)
This commit adds CJS/ESM interoperability when running in --compat mode.

Before executing files, they are analyzed and all CommonJS modules are
transformed on the fly to a ES modules. This is done by utilizing analyze_cjs()
functionality from deno_ast. After discovering exports and reexports, an ES
module is rendered and saved in memory for later use.

There's a caveat that all files ending with ".js" extension are considered as
CommonJS modules (unless there's a related "package.json" with "type": "module").

compat: support --compat in web workers (#13629)
Adds another callback to WebWorkerOptions that allows to execute
some modules before actual worker code executes. This allows to set up Node
global using std/node.

feat(compat) preload Node.js built-in modules in global vars REPL (#13127)
This commit adds preloading of built-in Node.js modules in
the REPL if running with "deno repl --compat --unstable".

compat: support compat mode in REPL (#12882)
This commit introduces "ProcState::maybe_resolver" field, which
stores a single instance of resolver for the whole lifetime of the
process, instead of creating these resolvers for each creation
of module graph. As a result, this resolver can be used in fallback
case where graph is not constructed (REPL, loading modules using
"require") unifying resolution logic.

chore: speed up compat tests (#12884)
This commit speeds up compat tests by using local copy of "deno_std"
instead of downloading it from https://deno.land for each test.
Additionally type checking is skipped.

feat(compat): integrate import map and classic resolutions in ESM resolution (#12549)
This commit integrates import map and "classic" resolutions in
the "--compat" mode when using ES modules; in effect
"http:", "https:" and "blob:" imports now work in compat mode.

The algorithm works as follows:

1. If there's an import map, try to resolve using it and if succeeded
return the specifier
2. Try to resolve using "Node ESM resolution", and if succeeded return
the specifier
3. Fall back to regular ESM resolution

feat(unstable): Node CJS and ESM resolvers for compat mode (#12424)
This commit adds CJS and ESM Node resolvers to the "--compat" mode.

The functionality is spread across "cli/compat" module and Node compatibility
layer in "deno_std/node"; this stems from the fact that ES module resolution
can only be implemented in Rust as it needs to directly integrated with 
"deno_core"; however "deno_std/node" already provided CJS module resolution.

Currently this resolution is only active when running a files using 
"deno run --compat --unstable <filename>", and is not available in other
subcommands, which will be changed in follow up commits.

feat(compat): inject Node globals (#12342)
This commit adds automatic injection of Node globals when "--compat" flag
is present.

This is done by executing "https://deno.land/std/node/global.ts" as a "side module",
before main module is executed.

This commit makes "--compat" required to be used with "--unstable" flag, as some
of Node globals require unstable Deno APIs.

feat: add --compat flag to provide built-in Node modules (#12293)
This commit adds "--compat" flag. When the flag is passed a set of mappings for
built-in Node modules is injected into the import map. If user doesn't
explicitly provide an import map (using "--import-map" flag) then a map is
created on the fly. If there are already existing mappings in import map that
would clash with built-in Node modules a set of diagnostics is printed to the
terminal with suggestions how to proceed.
