Relates to KT-8834, we continue reducing differences between old and new
inference. Note that as for `SamConversionPerArgument`, this feature
is enabled in the compiler and not in the IDE to avoid breaking code
for those users that already enabled new inference in the compiler
The kotlin-scripting-compiler-impl jar is used in the idea plugin and
therefore should not depend on the cli parts of the compiler to avoid
dependency from the plugin to the kotlin-compiler.jar.
Therefore the cli-dependent parts were moved to the scripting plugin
jar, which is used only in cli compiler based environments.
Also implement required abstractions to allow this movement and
drop some redundant dependencies to the cli parts in other projects.
Before 5b7cee6221 JVM CLI compiler
was calling `KotlinToJVMBytecodeCompiler.compileBunchOfSources`.
`compileBunchOfSources` detected possible main classes,
and filled the Main-Class attribute in output jar
if if there was only one candidate.
After the change JVM CLI began calling
`KotlinToJVMBytecodeCompiler.compileModules`, which was not searching for a main class.
This change adds searching for main classes to `compileModules`.
We search for a main class only when one module is compiled,
and an output is written a jar file (so the change only affects JVM CLI compilation).
#KT-32272 Fixed
If new inference is enabled only for IDE analysis, then this feature
will be disabled to reduce difference between new and old inference,
but if new inference is enabled in the compiler, then this feature
will be enabled too to preserve behavior of new inference for
compilation

'ServiceLoader' in JDK8 leaks file handles (https://bugs.openjdk.java.net/browse/JDK-8156014).
New implementation uses the ZipFile API, it also doesn't operate on the whole classpath which is not often needed.
There are two visible effects of this change:
1) If an empty argument is passed in quotes, it will be parsed as an
empty string and handled by the compiler, which will report an error
later. The specific error is not very important because it's an edge
case anyway; at the moment, "source file or directory not found:" is
reported which is no better than the "invalid flag:" error reported
by javac in the similar case
2) It's no longer possible to split an argument into several parts and
quote them separately, such as:
"-langu"ag"e-"ver'sio'n 1.2
No test added for this change in behavior since it's an even edgier
case. Note that javac also prohibits this.
#KT-27226 Fixed
- treat a contiguous whitespace sequence as a single argument separator,
not as several empty-string arguments separated by whitespaces
- fix infinite loop when reading unfinished quoted argument
- do not attempt to perform escape if the backslash is the last
character in the file
Arguments are passed in form '-XXLanguage:+LanguageFeatureName' for enabling
LanguageFeature.LanguageFeatureName, and '-XXLanguage:-LanguageFeatureName'
for disabling.
Note that they do override other settings, including 'language-version'
or extra ('-X') args.
In this mode, instead of analyzing files and generating bytecode for
them, compiler just saves imports of each file in JSON map of form
'<path to file> -> [<import1>, <import2>, ...]'
It is needed for some external tools, notably for Google3 toolchain.

Drop Experimental.changesMayBreak, Experimental.Impact, the concept of
signature/body usage, same module exemption. Make the majority of tests
single-module because there is now no difference in the checker between
usages from the same module or from another module
