Unreviewed build fix.

Remove unused source files to fix builds that don't strip symbols.

* Source/ThirdParty/libwebrtc/libwebrtc.xcodeproj/project.pbxproj:
- Let Xcode have its way with the project file by re-ordering files from
  41AB330F2B1F8D7700CEC7AE to 41AB33172B1F8D7700CEC7AE.
- Remove vp9_firstpass.{c,h} as this code is unused with
  CONFIG_REALTIME_ONLY=1.
- Remove vpx_convolve8_neon_asm.{c,h} since they create duplicate
  symbols for vpx_convolve8_neon.{c,h}.
- Remove vpx_convolve8_*_neon.asm files since we don't build assembly
  sources (using yasm) for Apple silicon architectures.
