Dev-mode build

[tjkirch]

I'd like to be able to build more quickly during development by using a mode that disables LTO, high optimization levels, and other features that are meant for release performance.

I think cargo-make might support something like this natively, given that I see Finished dev [optimized] in my builds, and their site shows Finished dev [unoptimized + debuginfo] on some examples? Also curious about that dev keyword.

I thought I was doing this in #578 but need to read more carefully. 😄

I expect we still want this even though we aren't doing LTO for release builds at the moment. Turning off debuginfo packaging should provide a nice speed-up.

My current thinking is that we could have another file under macros that corresponds to the Bottlerocket profile we're building, and the "dev" version of the macros could tweak debuginfo and optimization behavior.
