Fix missing headers in GN/GYP build files

While porting libyuv's GN to other build systems, I discovered that
several headers were absent in the GN and GYP build files. These headers
are utilized in the source files but were not included in the GN and GYP
build configurations.

Without these headers, the Bazel build fails with the following error:
ERROR: /path/to/bazel/external/libyuv/BUILD.bazel:4:11: Compiling source/compare.cc failed: (Exit 1): clang-17 failed: error executing CppCompile command (from target @@libyuv//:libyuv) /usr/bin/clang-17 -U_FORTIFY_SOURCE -fstack-protector -Wall -Wthread-safety -Wself-assign -Wunused-but-set-parameter -Wno-free-nonheap-object -fcolor-diagnostics -fno-omit-frame-pointer '-std=c++14' ... (remaining 32 arguments skipped)

Use --sandbox_debug to see verbose messages from the sandbox and retain the sandbox build root for debugging
