Moved all the threading code to one place. Added explicit support for
Darwin, Linux, Pthreads, C11 threads and Win32 threads, including new
implementations of Once for Linux, Pthreads, C11 and Win32.

SWIFT_STDLIB_SINGLE_THREADED_RUNTIME is too much of a blunt instrument here.
It covers both the Concurrency runtime and the rest of the runtime, but we'd
like to be able to have e.g. a single-threaded Concurrency runtime while
the rest of the runtime is still thread safe (for instance).
So: rename it to SWIFT_STDLIB_SINGLE_THREADED_CONCURRENCY and make it just
control the Concurrency runtime, then add a SWIFT_STDLIB_THREADING_PACKAGE
setting at the CMake/build-script level, which defines
SWIFT_STDLIB_THREADING_xxx where xxx depends on the chosen threading package.
This is especially useful on systems where there may be a choice of threading
package that you could use.

Currently, SwiftCompilerSources' inclusion of the regex parser depends on CMake flag `SWIFT_ENABLE_EXPERIMENTAL_STRING_PROCESSING`. However, in some scenarios we want to build the regex parser as part of the compiler _without_ building the runtime modules. This patch makes building the regex parser the default regardless of `SWIFT_ENABLE_EXPERIMENTAL_STRING_PROCESSING`. Only when the build environment is missing the string processing repo, we skip building the regex parser by setting `SWIFT_BUILD_REGEX_PARSER_IN_COMPILER` to false.
This patch adds a zlib and static-zlib build product, respectively
producing a dynamic and static zlib library. This is a dependency of
building Foundation.
Crash reporter integration was only enabled for iOS. Enable it for
any Darwin platform, but disable it for the minimal build.
Also fix up a couple of issues that popped up when it was enabled.

Since Swift is dropping Python2 support, and since this xcrun line causes
spurious errors during a build-script build on systems without Python2,
I am proposing we drop this xcrun -find line from build-script-impl.
Concurrency tracing was enabled depending on the presence of a header
file, but if a similarly named header was found somewhere in the path
that didn't do the same thing, that might cause problems.
Instead, we should have a build time configuration option.

This will let us save some build time without losing the coverage of
sil-verify-all everywhere since much of the code in all of the stdlibs are the
same.
This reverts commit a67a0436f7, reversing
changes made to 9965df76d0.
This commit or the earlier commit this commit is based on (#40531) broke the
incremental bot.
- Checkout apple/swift-experimental-string-processing using a tag.
- Build `_MatchingEngine` as part of libswift (`ExperimentalRegex`) using sources from the package.
- Parse regex literals using the parser from `_MatchingEngine`.
- Build both `_MatchingEngine` and `_StringProcessing` as part of core libs using sources from the package.
- Use `Regex<DynamicCaptures>` as the default regex type until we finalize apple/swift-experimental-string-processing#68.
Building the tests has been disabled when cross-compiling the toolchain almost from the beginning, but #39130 enabled building the test binaries by default again, so I had to locally disable building those tests when cross-compiling a standalone stdlib for Android.
The latest Long Term Support NDK finally removed binutils, including the bfd/gold
linkers and libgcc. This simplifies our Android support, including making lld the
default linker for Android. Disable three reflection tests that now fail, likely
related to issues with swift-reflection-dump and switching to lld.
