Skip-Lint: cherry pick of #51794

* chore: bump chromium in DEPS to 150.0.7863.0

* 7872896: [iOS Blink] Fix build breaks in ca_layer_tree_coordinator.mm

Upstream relocated the closing brace of the `if (!ca_context_)` block
to after `#endif // !BUILDFLAG(IS_IOS) || BUILDFLAG(IS_IOS_TVOS)`.
Repositioned the MAS `#endif` accordingly so the IS_MAS_BUILD guard
still wraps the entire function body.

* 7839163: Reland "Roll out Apple Linker for macOS non-official builds"

Upstream moved the use_thin_lto declaration to an earlier
declare_args() block and folded is_mac + (is_ios && use_lld) into a
single is_apple condition. Re-targeted the patch at the new location
and replaced is_apple with is_ios so thin LTO remains disabled on
macOS while staying enabled for iOS.

* 7867233: text-fit: Rename FitText, FitTextType, FitTextTarget, and FitTextMethod

Upstream renamed FitText -> TextFit (and ConvertFitText ->
ConvertTextFit). Updated the corner-smoothing patch's surrounding
declarations and definitions to match the new name, keeping the
inserted ConvertCornerSmoothing entry just before ConvertTextFit.

* chore: update patches

* 7777607: Replace ui::DomKey implicit constructor with C++17 inline constexpr

Upstream made ui::DomKey's integer constructor explicit, so the
implicit conversion from uint32_t no longer works. Cast
WebKeyboardEvent::dom_key to ui::DomKey explicitly before calling
DomKeyToKeyString.

* 7872317: [Extensions] Remove duplicate type entries from Manifest::Type

Upstream removed the SCREAMING_ENUM_STYLE aliases on
extensions::Manifest::Type. Switched from TYPE_EXTENSION to
Type::kExtension.
