ci: add support for building Win-ARM64 wheels

[MugundanMCW]

• The adoption of Windows on ARM (WoA) devices is steadily increasing, yet many Python wheels are still not available for this platform.
• GitHub Actions now offer native CI runners for Windows on ARM devices (windows-11-arm), enabling automated builds and testing.
• Currently, official tokenizers Python wheels are not provided for Windows ARM64 and thus users/developers were facing difficulties using popular tokenizers library natively.
• This PR introduces support for building tokenizers wheels on Windows ARM64, improving accessibility for developers and end users on this emerging platform.

In principle yes.

Note for @ArthurZucker : When CI was added and support for ARM added, Windows had tons of bugs making it impossible for us to release.
I hope it works better now.

Can we remove this weird condition, and have 2 target names if it's really needed ? Why isn't the target named aarch64 ?

[MugundanMCW]

Hi @Narsil,
The reason for using a separate Python target name for Windows on ARM is that the official Python GitHub Action only supports the architectures x86, x64, and arm64 for Windows [Reference]. Specifying aarch64 for Windows on ARM64 results in an invalid configuration, which causes the CI to fail.

[Narsil]

I know, but then maybe we could have "platform.target" and "platform.architecture" be defined in the matrix, which should make the flow easier to read.

@Narsil thanks for the suggestions, made the relevant changes

[ArthurZucker]

sounds good!
