Add macro definition functions DEF_SIGHANDLER_FUNC() and DEF_INST_RAISE_SIG() helpers.
Furthermore, there is no need to modify the default SIGILL handling function throughout the entire testing lifecycle in the main() function. It is reasonable to narrow the scope to the context of the sig_fn function only.
This is a pre-patch for the subsequent SIGBUS handler patch.

Some enhanced features, such as the LSE2 feature, do not result in SILLILL if LSE2 is missing and LSE is present, but will generate a SIGBUS exception when atomic access unaligned.
Therefore, we add test item to test this type of features.
Notice that testing for SIGBUS only makes sense after make sure that the instruction does not cause a SIGILL signal.

Add the LSE and various features check in the set of hwcap tests.
As stated in the ARM manual, the LSE2 feature allows for atomic access to unaligned memory. Therefore, for processors that only have the LSE feature, we register .sigbus_fn to test their ability to perform unaligned access.
