[cmake] Move a bunch of test binaries from install component 'tools' -> 'testsuite-tools'.

[gottesmm]

All of these are tools that are only meant to be used when testing swift. Thus
it doesn't make sense to include them in the catch all 'tools' install component
that distributions use to build all the tools.

I verified that all of the mac/linux presets in tree that have tools also has
testsuite-tools so this should be NFC. On Windows, I needed to add
testsuite-tools to build-windows.bat so should be NFC there as well.

Thanks! This definitely should help improve the CI space usage on Windows.

Some measurements - this reduced the build artifacts from 3.9G to 3.5G.

@compnerd just a FYI, I am checking with some people to make sure my guesstimates on what we can remove here is correct.

[compnerd]

@gottesmm - sounds good; I would be more clear though - it isn't being removed, only being given additional control when building with the LLVM distribution mechanism. If you use a standalone Swift build, this will not have any impact.

LGTM for swift-ide-test, swift-syntax-parser-test and swift-syntax-test.

[gottesmm]

I removed swift-ide-test since I think some people depend on it. I think I am going to include it in a different category though.
