[Java] mavencentral jars do not ship with libarrow_cdata_jni binding for linux/aarch64

[jonathanswenson]

Describe the bug, including details regarding any error messages, version, and platform.

Attempting to use the CData interface from java on linux/aarch64 fails with an exception on recent versions when using the maven central distributions:

java.lang.IllegalStateException: error loading native libraries: java.io.FileNotFoundException: aarch_64/libarrow_cdata_jni.so

Works just fine on mac (m1).

Appears the mavencentral distribution does not include the .so file for aarch64 (it does for x86).

Looks gandiva and dataset jars on mavencentral also do not have distributions with these.

We need to build aarch64 binaries by

arrow/dev/tasks/java-jars/github.yml

Lines 24 to 50 in 947a446

We can use self-hosted aarch64 runner for it:

arrow/dev/tasks/linux-packages/github.linux.yml

Took a stab at this here: #36487.

My main concern is pushing the Docker image for both aarch64 and x86, but I likely also do not fully understand the implications of everything I'm changing here.
