Fix the Node `process_priority` description to match actual behavior

This closes #34531.

Fix buffers size calculation in PacketPeerStream.

The calculation used to be wrong when exactly at a power of 2.
`nearest_shift` always return the "next" power of 2
`nearest_shift(4) == 3 # 2^3 = 8`.

On the other hand `next_power_of_2` returns the exact value if that
value is a power of 2 (i.e. `next_power_of_2(4) == 4`).

I.e. :
```
WARN_PRINT(itos(next_power_of_2(4)) + " " + itos(1 << nearest_shift(4)));
// WARNING: ... : 4 8
```

Is this by design?

Also fix a few stray clang-format formatting errors that passed
through CI unnoticed.

Mono/C#: Remove GodotTools dependency on the Mono.Posix assembly

We wanted 8 MiB but we were getting 16 MiB (minus 4 bytes for the
separator). We are now getting 8 MiB minus 4 bytes for encoding.

Used to spit error and report empty packets when connection was still
half-closed (waiting for confirmation from other end).

MSBuild on Windows uses the system .NET Framework BCL instead of Mono's. Because
of this, it may not be able to find the Mono.Posix assembly, so it's better
not to depend on it. We needed Mono.Posix to call Syscall.access, so we can
replace this with an internal call that does the same in C++.

Makes more editor strings translatable

Mention that bbcode_text += string is a bad idea

* "Add" button text in Groups Editor
* "Receiver Method" in Connect Signal Dialog
* "Play Mode" in Animation State Machine Editor
* "Mesh Library" button text in Mesh Library editor plugin
* Compose Array node button texts in Visual Script
* Various button texts in TileSet Editor
* Various Run Script errors

Mention how to handle cancel in ConfirmationDialog

The different Rect used to draw rings were wrongly calculated when anti-aliasing was enabled. Also getting rid of some overlapping glitches when using transparent colors for the filling or borders.
