Some maintenance on implementation and tests:
* Drop manual TargetMachineBuilder setup
* Drop addDebugSupport() in favor of Orc's enableDebuggerSupport()
* Check that debug support plugins append jit_code_entry
* Update and reduce sample input
https://github.com/llvm/llvm-project/pull/74764 reported that the
`lljit-with-remote-debugging` test fails on AArch64 hosts, because the
input IR file states arch x86_64 explicitly. In order to drop the target
triple we have to remove a check in the example implementation.
Not sure it's fully portable now, but at least it's better than before.
These were previously re-enabled in d771f54107c, but had to be disabled again
in 2060a72b4d7 due to test failures.
This is a next step to landing https://reviews.llvm.org/D148192, which adds
a skeleton JITLink backend for PowerPC.
The fixes for those failures were (1) to explicitly specify IsLittleEndian =
true for the MachO YAML testcases, (2) disable some example tests for examples
that aren't supported on PowerPC yet, and (3) fixing the endianness of a
relocation read/write (for ELF R_AARCH64_TSTBR14) in RuntimeDyldELF.
This is for case when native target like X86 is not in LLVM_TARGETS_TO_BUILD.
Right now LLVM_DEFAULT_TARGET_TRIPLE is set to LLVM_HOST_TRIPLE even when native target is not enabled,
As a result, many lit tests will fail because default_triple is set for lit test but not enabled when build LLVM.

The test was removed temporarily in a539a847c9428e36722dcb43a1c953c9d66b7f0b to aid switching the RPC API in use in the LLJITWithRemoteDebugging example.

The example demonstrates how to use a module summary index file produced for ThinLTO to:
* find the module that defines the main entry point
* find all extra modules that are required for the build
A LIT test runs the example as part of the LLVM test suite [1] and shows how to create a module summary index file.
The code also provides two Error types that can be useful when working with ThinLTO summaries.
