Remove unnecessary includes

Manual removal of includes based on include-what-you-use's output,
filtered for includes that should be removed. The goal is to avoid
unnecessary build dependencies, reducing the amount of code that needs
to be rebuilt during incremental builds. The build time for fresh
rebuilds decreases by about 7% as the following experiment shows:

```
rm -rf build && ccache -C
cmake -H. -Bbuild -G Ninja \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_EXE_LINKER_FLAGS="-fuse-ld=lld -Wl,--threads"
/usr/bin/time -v ninja -C build -j32
```

Repeated execution for both develop and this branch producing the
following data, which less than 1s of variation across multiple runs:

develop:
```
  Command being timed: "ninja -C build -j32"
  User time (seconds): 2714.02
  System time (seconds): 203.75
  Percent of CPU this job got: 2833%
  Elapsed (wall clock) time (h:mm:ss or m:ss): 1:42.96
```

this PR:
```
  Command being timed: "ninja -C build -j32"
  User time (seconds): 2507.14
  System time (seconds): 189.95
  Percent of CPU this job got: 2822%
  Elapsed (wall clock) time (h:mm:ss or m:ss): 1:35.56
