Avoid standing the Objective-C runtime lock by calling objc_copyRealizedClassList_nolock instead of objc_copyRealizedClassList. We already guarantee that no other threads can run while we're running this utility expression, similar to when we parse the data ourselves from the gdb_objc_realized_classes struct. Worst case this will crash if the list is getting edited, which won't do any harm and we'll just try again later.

…st_nolock When we check whether the Objective-C SPI is available, we need to check for the mangled symbol name. Unlike `objc_copyRealizedClassList`, which is C exported, the `nolock` variant is not. Differential revision: https://reviews.llvm.org/D105136 (cherry picked from commit 71be4db)

This test was originally xfailed because of a bug on iOS. This has since been fixed, so reenabling the test. (cherry picked from commit 05e48ec)
on arm64e, pointer auth would catch this access violation before asan. sign the function pointer so pointer auth will ignore this violation and let asan catch it in this test case. rdar://79652167 Reviewed By: delcypher Differential Revision: https://reviews.llvm.org/D104828 (cherry picked from commit f26adaa)
