Improve IR printing CLI in forc

[ironcev]

Description

This PR:

• implements detailed control over printing of IR:
  • initial IR
  • IR after choosen optimization steps, with option to print only the steps that have actually modified the IR
  • final IR
• improves printed IRs by removing the confusing empty modules printed for every external library dependency.
• harmonizes names and descriptions of the optimization passes. The proposed convention is documented in the sway-ir/src/optimize/README.md file.
• harmonizes help comments of the shared compiler options (consistent separation between option title and additional info, wording, etc.)

Demo

'Print initial and final IR together with IR after each optimization step.
--ir all

'Print initial and final IR together with IR after each optimization step that has modified the IR.
--ir all modified

'Print only the final IR.
--ir final

'Print the IR after every "dce", "sroa", and "inline" optimization step.
--ir dce sroa inline

'Print the IR after every "dce", "sroa", and "inline" optimization step that has modified the IR.
--ir dce sroa inline modified

Breaking Changes

CLI

Instead of the existing --ir option without parameters we now have the same CLI option but with parameters. The existing --ir is equivalent to the new --ir final.

Build Profile

Instead of the existing print-ir of type bool, we now have the same print-ir build profile option with parameters. E.g.:

print-ir = { initial = true, final = false, modified = true, passes = ["dce", "sroa"]}
