LoongArch: BPF: Add fsession support for trampolines
Implement BPF_TRACE_FSESSION support in LoongArch BPF JIT. The logic
here is almost identical to what has been done in RISC-V JIT.
The key changes are:
- Allocate stack space for function meta and session cookies
- Introduce invoke_bpf() as a wrapper around invoke_bpf_prog() that
populates session cookies before each invocation
- Implement bpf_jit_supports_fsession() callback
