[CMake] Streamline code signing for debugserver and pass entitlements to extended llvm_codesign
Summary:
Use llvm_codesign to sign debugserver with entitlements.
Set global LLVM_CODESIGNING_IDENTITY from LLDB_CODESIGN_IDENTITY (if given).
Pass through ENTITLEMENTS from add_lldb_executable to add_llvm_executable.
Handle reconfigurations correctly.
We have a lot of cases, make them explicit:
(1) build and sign debugserver, if all conditions apply:
* LLDB_NO_DEBUGSERVER=OFF (default)
* On Darwin: LLDB_USE_SYSTEM_DEBUGSERVER=OFF (default)
* On Darwin: LLVM_CODESIGNING_IDENTITY == lldb_codesign
(2) use system debugserver, if on Darwin and any of:
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and found on system (explicit case)
* LLVM_CODESIGNING_IDENTITY != lldb_codesign and found on system (fallback case)
(3) debugserver will not be available, in case of:
* LLDB_NO_DEBUGSERVER=ON
* On Darwin: LLVM_CODESIGNING_IDENTITY != lldb_codesign and not found on system
(4) error state, in case of:
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and not found on system
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and LLDB_NO_DEBUGSERVER=ON
