Support aarch64-unknown-linux-gnu target

Description

Add support for aarch64-unknown-linux-gnu

Proposal

Support build on aarch64-unknown-linux-gnu first. Probably add a new CI job to cover this.

Running on this arch is planned but with a lower priority.

Additional context

how can we confirm that a target is supported?

I have an aarch64 mac, I can build and run the CeresDB locally, and it seems that most of the functions work as expected besides an SST error log occurred.

I run the CRUD example on README, and get all the correct responses.

Maybe there are some issues caused by cross compiling to address if we choose to build CeresDB by github actions, e.g. apache/horaedb-client-py#20.

how can we confirm that a target is supported?

We need to ensure chip, runtime os and dev toolchain are supported. To list a target as "supported" I think there are two steps:

• Have CI to prevent untested regression.
• Have the capacity and willingness to solve problems on that target quickly.

But sadly we don't have these two conditions 😣 So the target is "maybe support", or in other words, is Tire-2 priority compared to amd64-linux

haha, of course, CeresDB should focus on the rapid development currently

Closing since this issue has been quiet for a while, free free to reopen if others have requirements depending on this.
