This PR and commit adds a new IK system for 3D with the Skeleton3D node
that adds several new IK solvers, as well as additional changes and functionality
for making bone manipulation in Godot easier.
This work was sponsored by GSoC 2020 and TwistedTwigleg
Full list of changes:
* Adds a SkeletonModification3D resource
* This resource is the base where all IK code is written and executed
* Adds a SkeletonModificationStack3D resource
* This node oversees the execution of the modifications and acts as a bridge of sorts for the modifications to the Skeleton3D node
* Adds SkeletonModification3D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in it's own file
* Several changes to Skeletons, listed below:
* Added local_pose_override, which acts just like global_pose_override but keeps bone-child relationships intract
* So if you move a bone using local_pose_override, all of the bones that are children will also be moved. This is different than global_pose_override, which only affects the individual bone
* Internally bones keep track of their children. This removes the need of a processing list, makes it possible to update just a few select bones at a time, and makes it easier to traverse down the bone chain
* Additional functions added for converting from world transform to global poses, global poses to local poses, and all the same changes but backwards (local to global, global to world). This makes it much easier to work with bone transforms without needing to think too much about how to convert them.
* New signal added, bone_pose_changed, that can be used to tell if a specific bone changed its transform. Needed for BoneAttachment3D
* Added functions for getting the forward position of a bone
* BoneAttachment3D node refactored heavily
* BoneAttachment3D node is now completely standalone in its functionality.
* This makes the code easier and less interconnected, as well as allowing them to function properly without being direct children of Skeleton3D nodes
* BoneAttachment3D now can be set either using the index or the bone name.
* BoneAttachment3D nodes can now set the bone transform instead of just following it. This is disabled by default for compatibility
* BoneAttachment3D now shows a warning when not configured correctly
* Added rotate_to_align function in Basis
* Added class reference documentation for all changes

Note: It still needs some work.
This was removed in #63481, and we confirmed that it's better like this,
but we add back the possibility to strip CR as an option, to optionally
restore the previous behavior.
For performance this is done directly in `String::parse_utf8`.
Also fixes Android `FileAccess::get_line()` as this one _should_ strip CR.
Supersedes #63717.

- Accelerate common path used to check the storage scope for a given path
- Update the logic for the `get_as_text()` method - previous logic loads the content of a text file one byte at a time

Read/write ops for this implementation are done through the java layer via jni, and so for good performance, it's key to avoid numerous repeated small read/write ops due the jni overhead.
The alternative is to allocate a (conversatively-sized) large buffer to reduce the number of read/write ops over the jni boundary.
This was done by refactoring directory and file access handling for the Android platform so that any general filesystem access type go through the Android layer.
This allows us to validate whether the access is unrestricted, or whether it falls under scoped storage and thus act appropriately.

Otherwise we would crash if something prints an error before init or
after destruction of the `OS` singleton which handles printing/logging.

Having a mix of settings with and without subcategory makes the 'Editor'
section stand out with a weird UX, as instead of simply being a foldable
section like the others, it also holds its own top-level settings and is
therefore selectable.
This wasn't the case in 3.4, and is fixed in 4.0 by refactoring, so for
3.5 we should preserve the 3.4 UX, even if it's not the best.

The methods disconnect_points and are_points_connected now have an optional p_bidirectional parameter matching AStar.

Backports features and bugfixes from current Godot 4.0 to 3.5 and brings functions and codebase of both version largely in sync to make tutorials more compatible and future backports easier.

Some compilers (notably MSVC) were using signed values for bitfield enums. This was causing problems where 2 bits were used to store 4 or less enum values, where they were being treated as negative numbers.
This PR explicitly requests these enums to be treated as unsigned values.
The rationale behind the expected number of bytes is now displayed
in clear (width, height, format, number of mipmaps expected if any).

References to "idle time" are progressively being replaced by
"process time" throughout the engine to avoid confusion.
This also changes some debug prints to be printed only when verbose
mode is enabled (like in `master`).
Allow AStar/AStar2D zero point weight.
Limit was set to 1 which seemed like an arbitrary value as lower values down to zero can be useful for common gameplay navigation elements like teleports.
Adds the is_process_running function to the native OS class and exposes it to script.
This is implemented on Windows and Unix platforms. A stub is provided for other platforms that do not support this function.
Documentation is updated to reflect new API function. - mdavisprog

I did change it a bit.
Leftover transforms from the physics tick were being flushed during idle, which was causing problems for physics interpolation.
This PR flushes the transforms at the end of the physics tick when physics interpolation is active.
