Added SortList class, and updated List, SelfList, and HashMap sort methods to use it. Sorting is done with merge sort, with an initial check to optimize for already sorted lists, and sorted lists that were appended to.
We don't seem to expose any API that uses `char16_t` yet, but I added it anyway since we make the type info for it.
I didn't add anything for `wchar_t` because we are not making a type info so maybe we don't have a need for it yet, it could be added in the future.
To prevent breaking compatibility with the C# bindings, we ignore the `char32_t` metadata and still use `System.Int64`.
* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
Random-access access to `List` when iterating is `O(n^2)` (`O(n)` when
accessing a single element)
* Removed subscript operator, in favor of a more explicit `get`
* Added conversion from `Iterator` to `ConstIterator`
* Remade existing operations into other solutions when applicable
Instead of making the accessors `internal` which can break binary compat, make them `public` but hide them with EB never so they don't show up in IntelliSense.
Also, do the same for properties with the `PROPERTY_USAGE_INTERNAL` flag. These properties were not meant to be exposed to scripting, but since they've been public before all we can do now is hide them.
New rules:
- Do not silence CA1805 any more
- Limit where we silence CA1707, CA1711, CA1720
- Enforce severity=warning for IDE0040
- Enforce Allman style braces
- Enforce naming conventions (IDE1006 is still severity=suggestion)
Fixes:
- Fix REFL045, CS1572, CS1573
- Suppress CS0618 when generating `InvokeGodotClassMethod`
- Fix indent when generating GD_constants.cs
- Temporarily silence CS1734 in generated code
- Fix a lot of naming rule violations
Misc.:
- Remove ReSharper comments for RedundantNameQualifier
- Remove suppression attributes for RedundantNameQualifier
- Remove severity=warnings for CA1716, CA1304 (already included in the level of analysis we run)
