feat: support samply profiler for packaged apps on macOS

https://github.com/mstange/samply is amazing to profile
Electron apps that need visualization of both JS and native
samples in an unified view. However, we cannot use the profiler
once the application is packaged due to restrictions from
entitlements and SIP that will disallow loading the preload library
from samply to exchange the task ports from the launched process.

This changes takes an alternative route inspired by crashpad architecture
where the samply profiler will be bundled as part of the application,
the browser process launches the profiler on demand and performs
mach port exchange via a simple handshake protocol implemented in
950b80e711
Every child process then launched by the browser will send their
task ports via the verified ipc connection the browser process
has created with the samply profiler process.

NB: the --samply-path is for testing purpose, we should remove it
and bundle the samply executable next to chrome_crashpad_handler
when packaging so that evil actors cannot hijack the ipc.

+### Behavior Changed: Offscreen rendering will use `1.0` as default device scale factor.
+
+Previously, OSR used the primary display's device scale factor for rendering, which made the output frame size vary across users.
+Developers had to manually calculate the correct size using `screen.getPrimaryDisplay().scaleFactor`. We now provide an optional property
+`webPreferences.offscreen.deviceScaleFactor` to specify a custom value when creating an OSR window. At first, if the property is not set, it defaults
+to the primary display's scale factor (preserving the old behavior). Starting from Electron 42, the default will change to a constant value of `1.0`
+for more consistent output sizes.

patches/chromium/disable_compositor_recycling.patch

@@ -6,7 +6,7 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.
