electron-roller[bot] 6aaf490aa5 chore: bump chromium to 148.0.7768.0 (main) (#50599)
* chore: bump chromium in DEPS to 148.0.7765.0

* chore: bump chromium in DEPS to 148.0.7766.0

* fix(patch-conflict): update packed_resources dep name after upstream rename

Upstream renamed //chrome:packed_resources_integrity_header to
//chrome:packed_resources. Updated the patch to guard the new dependency
name with !is_electron_build while preserving the same intent.

* fix(patch-conflict): update code_cache_host_impl.cc for upstream includes and TODO

Upstream added #include <stdint.h> and a TODO comment in
code_cache_host_impl.cc which conflicted with the Electron code cache
custom schemes patch. Resolved by keeping both upstream additions and
the Electron ProcessLockURLIsCodeCacheScheme function.

* 7700837: update RecordContentToVisibleTimeRequest from mojom to native struct

Upstream typemapped RecordContentToVisibleTimeRequest from a Mojo
struct to a native C++ struct. Updated OSR virtual method signatures
from blink::mojom::RecordContentToVisibleTimeRequestPtr to
std::optional<blink::RecordContentToVisibleTimeRequest> and
blink::RecordContentToVisibleTimeRequest to match.

* 7714579: update WebString::FromASCII to FromUTF8

Upstream renamed blink::WebString::FromASCII to FromAscii. Updated
Electron's usage to FromUTF8 which is equivalent for ASCII scheme
strings and avoids a dependency on the renamed method. Also fixed
blink::String::FromUTF8 to use the String constructor directly.

* 7696480: add stream_info dep after StreamInfo extraction

Upstream extracted extensions::StreamInfo from PdfViewerStreamManager
to a standalone class in extensions/browser/mime_handler/stream_info.h.
Added the new target as a dependency since Electron's streams_private
and pdf_viewer_private APIs use PdfViewerStreamManager which now
depends on the separate StreamInfo target.

* fix(patch-conflict): update PiP patch for new toggle_mute_button in overlay window

Upstream added a toggle_mute_button to the live caption dialog controls
in VideoOverlayWindowViews::SetLiveCaptionDialogVisibility. Extended the
existing #if 0 guard to include the new button handling since Electron
disables live caption dialog functionality.

* fix(patch-conflict): update packed_resource_integrity patch after upstream dep removal

Upstream removed the deps += [ "//chrome:packed_resources" ] line from
the if (!is_win) block in chrome/browser/BUILD.gn. The Electron patch
no longer needs to guard this dep with !is_electron_build in this
location since the dep was already relocated by an earlier upstream CL.

* fix(patch-conflict): update WebSocket throttling revert for DisconnectWebSocketOnBFCache guard

Upstream added a DisconnectWebSocketOnBFCacheEnabled() runtime feature
check that wraps the WebSocket BFCache feature registration. Updated the
Electron revert patch to place the kAllowAggressiveThrottlingWithWebSocket
ternary inside the new conditional guard.

* fix(patch-conflict): update SCContentSharingPicker patch for upstream native picker refactor

Upstream added is_native_picker and filter_ based native picker session
validation to ScreenCaptureKitDeviceMac. Electron's patch uses its own
native picker approach (active_streams_ counter + direct SCContentSharingPicker
API), so marked the new upstream parameters as [[maybe_unused]] and kept
Electron's implementation.

* 7708800: update StartDragging signature to use RenderFrameHost

Upstream refactored StartDragging to take a RenderFrameHost& instead of
separate source_origin and source_rwh parameters. Updated
OffScreenWebContentsView to match the new signature and derive the
RenderWidgetHostImpl from the RenderFrameHost internally.

* 7682308: add toggle_mute_button to chromium_src build sources

Upstream added a ToggleMuteButton to the PiP overlay window controls.
Added the new toggle_mute_button.cc/h source files to Electron's
chromium_src/BUILD.gn to resolve linker errors.

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.
