Subject: [PATCH] SWDEV-294596 - Fix module test failure on NV

1.Fix hipModuleNegative failure on all NV GPUs
a.Add signal handler for signal sent by cuda functions.
b.Make hipModuleGetGlobal match cuModuleGetGlobal behavour.
That is, if one of the first two parameters is nullptr, ignore it.

2.Fix hipModuleLoadDataMultThreaded failure on NV RTX5000
Improve lamda function.
