Currently, on Windows, GTest cannot print 128-bit ints. We have a check in `test_utils::protected_assert_eq` that avoids calling `ASSERT_EQ` on 128-bit int values directly, since this will cause the values to be printed in the event of an error. This check was relying on the `is_int128` alias, which was being set to `false_type` when `ROCPRIM_HAS_INT128_SUPPORT` was `false`. As a result, when 128-bit types were passed in, our check could not detect them and would fail to stop the printing. In [rocprim/types.hpp](https://github.com/ROCm/rocm-libraries/blob/develop/projects/rocprim/rocprim/include/rocprim/types.hpp#L69), the types `rocprim::int128_t` and `rocprim::uint128_t` are now defined regardless of how `ROCPRIM_HAS_INT128_SUPPORT` is set. This means we no longer need to guard against usage of these types in our test code (we only need to use `ROCPRIM_HAS_INT128_SUPPORT` in cases where we're doing some operation that explicitly won't work on 128-bit ints). This change removes the code that sets the `is_int128` alias to `false_type` when `ROCPRIM_HAS_INT128_SUPPORT` is not set. Doing this is enough to fix the check in `test_utils::protected_assert_eq`.

Reverse UseGTestAssert condition on Windows
Recently, we added a check to see if GTest's ASSERT_EQ assertion
should be used within the assert_eq function. The code in the if/else
blocks that act on the results of this check was inverted (the "else"
code block should be the "if" block, and vice-versa).
This change fixes the issue by swapping the code blocks.
This change should be merged after #449.

The back port looks fine. To summarize it back ports the new config launch system, the ordered block id code and some small fixes.

As we add support for more GPU architectures, the size of the fat binary is growing. For some builds, it's large enough that we are running into linker errors because symbols are out of range. This change adds a cmake option called `BUILD_OFFLOAD_COMPRESS`, (defaults to `ON`) which enables/disables the `--offload-compress` compiler option. This option causes the compiler to compress the binary after it's generated. When the binary is run, it is decompressed in one shot on startup. The performance penalty for this decompression seems to be minimal. The reduction in size to the fat binary is significant for some targets (up to about 80% in some cases). It also removes these obsolete default build targets: gfx803, gfx900. Build rocPRIM for all default architectures. Ensure there are no linker errors. No linker errors locally - will wait for CI completion to confirm there as well. - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.

Motivation
See #1981 for full explanation. This feature/fix needs to be ported back to ROCm 7.0.x
Technical Details
Porting back 7.1 ordered block id changes to 7.0 codebase. I had to pull in some other (slightly) unrelated 7.1 code changes to make the porting work.
Also had to cherry pick 6c24aff to get the Windows job to pass.
Test Plan
Running CI.
