* feat: add a new contextBridge module

* chore: fix docs linting

* feat: add support for function arguments being proxied

* chore: ensure that contextBridge can only be used when contextIsolation is enabled

* docs: getReverseBinding can be null

* docs: fix broken links in md file

* feat: add support for promises in function parameters

* fix: linting failure for explicit constructor

* Update atom_api_context_bridge.cc

* chore: update docs and API design as per feedback

* refactor: remove reverse bindings and handle GC'able functions across the bridge

* chore: only expose debugGC in testing builds

* fix: do not proxy promises as objects

* spec: add complete spec coverage for contextBridge

* spec: add tests for null/undefined and the anti-overwrite logic

* chore: fix linting

* spec: add complex nested back-and-forth function calling

* fix: expose contextBridge in sandboxed renderers

* refactor: improve security of default_app using the new contextBridge module

* s/bindAPIInMainWorld/exposeInMainWorld

* chore: sorry for this commit, its a big one, I fixed like everything and refactored a lot

* chore: remove PassedValueCache as it is unused now

Values transferred from context A to context B are now cachde in the RenderFramePersistenceStore

* chore: move to anonymous namespace

* refactor: remove PassValueToOtherContextWithCache

* chore: remove commented unused code blocks

* chore: remove .only

* chore: remote commented code

* refactor: extract RenderFramePersistenceStore

* spec: ensure it works with numbered keys

* fix: handle number keys correctly

* fix: sort out the linter

* spec: update default_app asar spec for removed file

* refactor: change signatures to return v8 objects directly rather than the mate dictionary handle

* refactor: use the v8 serializer to support cloneable buffers and other object types

* chore: fix linting

* fix: handle hash collisions with a linked list in the map

* fix: enforce a recursion limit on the context bridge

* chore: fix linting

* chore: remove TODO

* chore: adapt for PR feedback

* chore: remove .only

* chore: clean up docs and clean up the proxy map when objects are released

* chore: ensure we cache object values that are cloned through the V8 serializer

* docs: mark contextBridge as experimental (#20638)

* docs: mark contextBridge as experimental

This commit didn't make it to the original PR, quick addition here

* Update context-bridge.md

* chore: update for 7-0-x differences
