Add doctor check for unbrewed header files
wxmac: remove temporary 10.10 patch
wxmac: backport upstream fixes for 10.10

This includes all of the change sets from the upstream wxwidgets project that
correctly build for 10.10, as well as 10.9 (and earlier.) These changes are
currently accepted in the upstream trunk, but will not be available until the
next release is cut (which will probably be a non-trivial amount of time after
10.10 releases.)

Generate RDoc documentation.

This is currently still very messy and we probably want to work out the
best way to declare what parts of our DSL/what files are "public".

Still, even if this is a WIP I'd rather get something committed sooner
rather than later and start iterating on this as a replacement for
`example_formula.rb` and the formula cookbook.

To test:
```bash
cd $(brew --prefix)/Library/Homebrew && \
  rdoc formula.rb requirement.rb utils.rb &&\
  open doc/index.html
```

Closes #32470.
brew: add contributed tap commands to PATH.

This means that taps root and `cmd` directories are added to the PATH.

This should enable migration of some of our contributed commands into
taps (e.g. `homebrew-boneyard`) and make it easy for third parties to
be able to maintain these. It might also make stuff easier for existing
tools like e.g. `brew-cask` and `boxen`.

Closes #32471.
