[vector_graphics_compiler] Use Abi.current() for engine-artifact lookup

On Linux ARM64 hosts, asset bundling fails with `Could not locate
libpathops at .../engine/linux-x64/libpath_ops.so`. Flutter ships the
engine binary at `.../engine/linux-arm64/...`, but
_initialize_path_ops_io.dart and _initialize_tessellator_io.dart
hardcode `'linux-x64'` on Linux.

Switch the Linux branch to pick `'linux-arm64'` when
Abi.current() == Abi.linuxArm64, otherwise keep `'linux-x64'`.
Behavior on existing hosts is unchanged.

Fixes flutter/flutter#158865.

+## 1.2.4
 
 * Updates minimum supported SDK version to Flutter 3.38/Dart 3.10.
+* Fixes `linux-arm64` host support by selecting the Flutter engine
+  artifact directory from `Abi.current()` instead of a hardcoded
+  `linux-x64`. The same fix applies to the tessellator loader.
+  Resolves flutter/flutter#158865.
