[KMP] Memory leak found in PublicKey

[10gic]

Describe the bug
I found a memory leak in PublicKey within the Kotlin package of Wallet Core.

To Reproduce
The following code can trigger a memory leak:

println("Test started")
val publicKeyHex =
    @Suppress("ktlint:standard:max-line-length")
    "044ba28b11af1561042b03b9d0f940446315af11358aa12d798050b3cf76265dab0f48b22ea1fc1f9560c969b966221f2821b746c4e56efaeaeec8689caf5843c9"
var i = 1
val publicKeyByteArray = publicKeyHex.hexToByteArray()
while (i <= 10_000_000) {
    val publicKey = PublicKey(publicKeyByteArray, PublicKeyType.SECP256k1Extended)
    if (i % 20_000 == 0) {
        println("Test case $i run")
    }
    i++
}
println("Test completed")

Expected behavior
No memory leak.

Hi @10gic, this issue duplicates #4021
As I mentioned before, GC doesn't have time to trigger the ReferenceQueue to clean up the memory. But in real life there shouldn't be the memory leak.
However, if there is something I'm wrong with, or miss something, I'd be happy to know

The root cause is completely different, so I opened a new bug.

I see @10gic, thanks. I'm investigating the bug, thank you!
