Add new options (hdri, tcmalloc, svt-av1), improve install methods

[coleplx]

What does this PR do?

This is still a draft PR containing a few changes and additions to imei. New options:

• --with-tcmalloc - Alternative memory allocator
• --disable-hdri - Passes --disable-hdri to ImageMagick: improves conversion time
• --with-svtav1 - Disables libaom default AV1 encoder, enabling SVT-AV1 instead - Faster encoder at the cost of file size

checkinstall changes: I noticed a few make errors in the logs and realized cmake lacks make uninstall. So, the system got tainted with leftovers even when --build-only was set.

The only alternative I found was to set --fstrans AND --install to yes when --build-only was set. fstrans=yes ensures checkinstall doesn't touch our real filesystem, and --install=yes instructs it to install the newly compiled package... it's a bit contradictory, but it's a requirement to compile all the libraries. After everything is ready, these packages are removed again.

Test Plan

Well, it's an ongoing task. I'll provide more details soonish.

Poem

🐇 In the meadow, changes bloom,
Scripts now dance, dispelling gloom.
SVT-AV1, a new delight,
With options bright, they take flight.

Huh, I found other serious issues with checkinstall + fstrans=yes... :disappointed:

I spent a few hours trying to workaround these issues, but things started to get way too complicated. I'll revert the fstrans changes tomorrow and think of another way to ensure all file dependencies are correctly installed.
