Subject: Output SPIR-V lifetimes (#2221)

* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP tracking liveness.

* Skeleton around adding liveness instructions.

* Calling into liveness tracking logic.
Adds live start to var insts.

* Liveness macros have initial output.

* Looking at different initialization scenarios.

* Some discussion around liveness.

* WIP for working out liveness end.

* WIP Updated liveness using use lists.

* Is now adding liveness information

* Some small fixes.

* WIP around liveness.

* Seems to output liveness correctly for current scenario.

* Tidy up liveness code.

* Update comment arounds liveness to current status.

* Small fixes to liveness test.

* Add support for call in liveness analysis.

* Improve liveness example with array access.

* Small updates to comments.

* Disable liveness test because inconsistencies with output on CI system.

* First pass support for GLSL SPIR-V liveness support.

* Add the SPIRVOpDecoration.

* Fix signature for OpLivenessStop.

* Simplified by having a Kind type.

* Fix some issues brought up in PR.

* Rename liveness instructions.

* Merge with var-lifetime.
Small improvements.

* Improvements to the documentation/naming in GLSL liveness pass.
Add comment around possible improvements to the liveness pass.
