Strip libmonosgen linked library

[directhex]

It seems in all Mono .symbols.nupkg packages, instead of a stripped .dylib/so and companion .dwarf/.dbg, we've just been shipping unstripped libs (and shipping unstripped libs in the non-symbols packages too). This commit largely duplicates the functions from eng/native/functions.cmake into an MSbuild proj, as our entire install logic is already in MSbuild not CMake. Moving to the common CMake functions would be a much larger task.

This should reduce our install size, and better mirror the rest of dotnet's debug infra & behaviour.

This probably also fixes #45013, though we should check we don't impact XA/XI.

What's the status of this PR?

[directhex]

I think it's fine, just running into flakiness in unrelated places in testing

[akoeplinger]

Retriggered the lanes just to be sure :)

@directhex we would need to strip libmono-component-*.so when doing dynamic components build (currently only on Android), something we could add into this PR as well?

@lateralusX how can i force a dynamic components build on... anything that isn't android? that's one platform i don't have the environment set up locally for

[directhex]

wait, docker, right. bleh

I hate docker

@lateralusX this is looking good locally

Sorry, just saw this, there is MonoComponentsStatic in mono.proj controling build, so not setting it or make sure cmake won't get -DSTATIC_COMPONENTS=1 should enable dynamic component builds.

What is the size of the stripped .so files?
