reduce latency of JLCall after loading other packages

[songjhaha]

function JLCall could get about 50s latency after loading a lot of big packages in julia 1.9

use Base.inferencebarrier to reduce this latency

[songjhaha]

here is the code about the performance:

using TyJuliaCAPI

function bench(n)
    fProxy = TyJuliaCAPI.JV_ALLOC(+)
    arg1Proxy = TyJuliaCAPI.JV_ALLOC(1.0)
    arg2Proxy = TyJuliaCAPI.JV_ALLOC(2.3)
    out = [JV()]
    args = [arg1Proxy, arg2Proxy]
    kwargs = Ptr{TyTuple{JSym,JV}}(C_NULL)
    Base.GC.enable(false)

    t1 = time_ns()
    GC.@preserve out args kwargs begin
        for i in 1:n
            ret = TyJuliaCAPI.JLCall(pointer(out), fProxy, TyJuliaCAPI.TyList(2, pointer(args)), TyJuliaCAPI.TyList(0, kwargs))
            TyJuliaCAPI.JV_DEALLOC(out[1])
        end
    end
    t2 = time_ns()
    Base.GC.enable(true)
    TyJuliaCAPI.JV_DEALLOC(fProxy)
    TyJuliaCAPI.JV_DEALLOC(arg1Proxy)
    TyJuliaCAPI.JV_DEALLOC(arg2Proxy)

    println("Time cost every call in $(n) loops: ", (t2 - t1) / n, " ns")
end

println("call first time to compile")
bench(1)
# v0.5.8 : cost per call: 20 ~ 30+ us
# this PR: cost per call: 20+ us

println("call second time to benchmark")
bench(1_000_000)
# v0.5.8 : cost per call: 334.5068 ns
# this PR: cost per call: 328.1931 ns
