devel/electron25: fix build with clang 18
Clang 18 has become more stringent about narrowing in initializer lists,
resulting in errors when building devel/electron25: ../../third_party/webrtc/pc/legacy_stats_collector.cc:191:54: error: non-constant-expression cannot be narrowed from type 'double' to 'float' in initializer list [-Wc++11-narrowing-const-reference] 191 | {StatsReport::kStatsValueNameTotalAudioEnergy, info.total_output_energy}, | ^~~~~~~~~~~~~~~~~~~~~~~~ ../../third_party/webrtc/pc/legacy_stats_collector.cc:193:8: error: non-constant-expression cannot be narrowed from type 'double' to 'float' in initializer list [-Wc++11-narrowing-const-reference] 193 | info.total_output_duration}}; | ^~~~~~~~~~~~~~~~~~~~~~~~~~
and later:
In file included from ../../cc/layers/mirror_layer_impl.cc:5: ../../cc/layers/mirror_layer_impl.h:59:40: error: non-constant-expression cannot be narrowed from type 'int' to 'unsigned long' in initializer list [-Wc++11-narrowing-const-reference] 59 | return viz::CompositorRenderPassId{mirrored_layer_id()}; | ^~~~~~~~~~~~~~~~~~~
The first batch of errors can be fixed similarly to bug 276997, by
cherry-picking https://webrtc.googlesource.com/src/+/267f9bdd53 into the
thirdparty directory.
The second batch of errors can be fixed by cherry-picking
https://chromium.googlesource.com/chromium/src/+/5e9fb4130a537.
