[compiler-rt][asan] Re-enable ManyThreadsTest on AArch64

[c-rhodes]

Disabled in 2ab51bf, doesn't hang for me on AArch64 (Graviton 3, tested 1000 iterations). May still be an issue, but hard to know unless we enable it again to find out.

n.b. test was also disabled on PowerPC in
467afc5 for same reason and it has also been observed on x86:

Fixes: #24763
