Some interfaces like Node, CharacterData and HTMLTableCellElement are never
instantiated directly, only their descendant interfaces are. Those are marked
with [Abstract] to set their type_id to None instead of having dummy values
in the TypeId enums.
After this pull request merged:
https://github.com/servo/servo/pull/7209
the 'script' component would never enter a 'built' state. In other
words, if one calls `mach build`, lets it complete, then calls `mach
build` again, the 'script' component would rebuild even though we
supposedly just built it. This was due to the `ParserResults.pkl`
getting placed in the `components/script` directory instead of the
output directory, causing cargo to think that there were unbuilt files.
Cleanup/refactor build scripts for DOM codegen
Prior to this commit, the script codegen makefile relied on an
intermediary pythonpath.py file that handled python dependencies and
incorporated a couple hacks to get the codegen building working. This
commit removes that intermediary file and attempts to make the script
codegen build process cleaner.

Generates `SupportedPropertyNames` on DOM structs that should implement
it. Most of them are unimplemented now (which can be implemented in
later PRs), with the exception of `HTMLCollection`. Also added a couple
relevant WPT tests.

`CGAbstractMethod` takes a couple boolean parameters, among others:
* `extern`: will mark the method as `unsafe` and `extern`
* `unsafe`: will wrap the method body in an `unsafe` block
Passing both as `True` should not mark it as `unsafe` twice.
Example from a generated `HTMLCollectionBinding.rs`:
Before:
```
unsafe extern fn get_length(..) -> u8 {
unsafe {
// code here
}
}
```
After
```
unsafe extern fn get_length(..) -> u8 {
// code here
}
```
Recently, I found myself reading through the Python codegen scripts that
live in 'components/script/dom/bindings/*' and noticed that there were
many tidy violations: unnecessary semicolons, weird spacing, unused
variables, lack of license headers, etc. Considering these files are now
living in our tree and mostly maintained directly by contributors of
Servo (as opposed to being from upstream), I feel these files should not
be excluded from our normal tidy process. This commit removes the
blacklist on these files and fixes all tidy violations.
I added these subdirectories to the blacklist because they appear to be
maintained upstream somewhere else:
* "components/script/dom/bindings/codegen/parser/*",
* "components/script/dom/bindings/codegen/ply/*",
Also, I added a '# noqa' comment which tells us to ignore the
flake8 errors for that line. I chose to ignore this (instead of fixing
it) to make the work for this commit simpler for me.
