Small SDK lookup fix (dotnet/core-setup#4807)

* Improve SDK version lookup description

Link to official docs which have detailed description of the algorithm.
Add a note about the hostfxr export options as well.

* Fix a small issue to avoid looking up directories like -1.-1.-1

If the global.json specifies SDK version but we can't find that version in a given search location, the code would end up checking if a folder with name "-1.-1.-1" exist. This is because we're left with empty version structure which is represented as -1.-1.-1.
Not only this is a small perf issue (unnecessarily looking at disk), but if the folder existed by any chance we would have returned that version for use.

Add new export to hostpolicy and hostfxr to redirect error output (dotnet/core-setup#4816)

* Add new export to hostpolicy and hostfxr to redirect error output to a callback

This introduces corehost_set_error_writer and hostfxr_set_error_writer exports.
If set, all errors will be written to the error writer instead of the default stderr.
Tracing is unaffected by this change.
The error writer is set per-thread (thread local).
Only one error writer can be set on a given thread. Subsequent calls to set error
writer will overwrite the previous writer.

hostfxr propagates the custom error writer (if any) to the hostpolicy
for the duration of the calls it makes to hostpolicy.

Added tests to validate the new behavior.

* Remove TODOs which are now resolved with this change

* Fix buffer allocation to work with any string (arbitrary large).
Remove locks on error writer since it's thread local.

* Fix the error formating on Linux

* Fix error formatting on Linux

va_list is not reusable, by definition. On Windows this works since the implementation makes it reusable. but on Linux it's not. So make a copy before calling the printf with it.

Simplify the code, since vsnprintf and _vsnwprintf do in fact behave the same if passed NULL buffer and zero length (calculates the necessary buffer size). So no need for two functions even on Windows.

Allow missing assembly dependencies for components. (dotnet/core-setup#4751)

When resolving assembly dependencies for components, don't fail if the assembly doesn't exist on the disk (but it's still present in the .deps.json as a runtime asset).
For dynamically loaded components this behavior makes sense as such components are typically distributed as just the necessary pieces, with everything else provided by the app.

This is a temporary change mainly as a workaround for dotnet/sdkdotnet/core-setup#2660. Issue dotnet/core-setupdotnet/core-setup#4752 is tracking future need for revisiting this change.

Refactor the helper project for host API tests (dotnet/core-setup#4629)

This makes the project modular - with ability to easily add tests for other APIs (the upcomming hostpolicy ones).
This is a pure refactoring, the only functional change is the addition of logging the full path to the hostfxr being used by the tests.

Implement the incremental build on Linux as well

Commit migrated from https://github.com/dotnet/core-setup/commit/af139963731ef1fbc43c754aaf6378c0287a697a

Add option to build the corehost incrementally

Currently the build script hardcodes clean rebuild of the native components in corehost. This makes it pretty slow for inner dev loop.
The same script also always clears all the intermediates which makes cmake perform all of the detections again which is also very slow.
This change adds a new build option -IncrementalNativeBuild=true which disables these two behaviors (don't delete intermediates, don't force a rebuild).

Also add a build option to build just the corehost subtree since that's a common task for devs working on the hosting components.

With this change empty incremental build (no changes made) of the corehost components is now less than 10 seconds. Change to a single cpp file takes less than 20 seconds to rebuild (as oppose to couple of minutes before).
