doc: Fix all Doxygen warnings, cleaning up some generated documentation

This makes Doxygen’s output more actionable by setting QUIET = YES to
suppress verbose progress spew, and WARN_IF_UNDOCUMENTED = NO to prevent
warnings for undocumented classes and members from being generated. The
latter is too noisy, producing 721 warnings in the current codebase.

The remaining warnings produced by Doxygen were useful and actionable.
They fell into two categories: abuses of Doxygen’s markup syntax, and
missing (or misspelled) parameter documentation. In a small number of
cases, pass-through parameters had intentionally been left undocumented.
In these cases, they are now given blank \param descriptions. This is
not optimal, but there doesn’t appear to be any other way to tell
Doxygen to allow a single parameter to be undocumented.

Some tricky Doxygen errors were resolved by asking it to not enter
directiores that we do not provide documentation in (such as the
“on-platform” compat directories, compat/mac and compat/win, as well as
compat/non_cxx11_lib) while allowing it to enter the
“off-platform” directories that we do document (compat/non_mac and
compat/non_win).

A Doxygen run (doc/support/generate_doxygen.sh) now produces no output
at all. It would produce warnings if any were triggered.

Not directly related, but still relevant to documentation,
doc/support/generate.sh is updated to remove temporary removals of
now-extinct files and directories. doc/appengine/README is updated so
that a consistent path to “goapp” is used throughout the file.
