Package decls were made to be resilient at the definition
site by default. By allowing the attributes to be applied
to package decls, we can enable non-resilient access.

SILOptions::EnableSerializePackage info is lost.
SILVerifier needs this info to determine whether resilience
can be bypassed for decls serialized in a resiliently
built module when Package CMO optimization enabled.
This PR adds SerializePackageEnabled bit to Module format
and uses that in SILVerifier.

Add the machinery to support suppression of inference of conformance to
protocols that would otherwise be derived automatically.
This commit does not enable any conformances to be suppressed.
When caching is enabled with include-tree, the bridging header PCH is
created from the include tree directly. Setup the rewriter correctly
when embedding the bridging header into swift binary module.

This change introduces a new compilation target platform to the Swift compiler - visionOS.
- Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target.
- Addition of the new platform kind definition.
- Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries.
- Utilities to read out Darwin platform SDK info containing platform mapping data.
- Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback').
- Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path.
- Changes to existing test suite to accomodate the new platform.
[Dependency Scanning] Use a standalone `DependencyScanningFilesystem`on the scanner, sharing a common `status` cache from Clang's dependency service cache
Sometimes, quotes or an "aka" for a type are not desirable in a
diagnostic, such as one describing a Requirement. This modifier
suppresses such additional formatting a Type in a diagnostic.
The attribute declares that a struct contains "sensitive" data.
It enforces that the contents of such a struct value is zeroed out at the end of its lifetime.
In other words: the content of such a value is not observable in memory after the value's lifetime.
Also add an experimental feature `Sensitive` with which the attribute can be enabled.
Specifically, I am transforming it from "may cause a race" -> "may cause a data
race". Adding data is a small thing, but it adds a bunch of nice clarity.
Teach scanner to pick and choose binary modules correctly based on if it
is testable import or not. Some situations that scanner need to be
careful when testable is involved:
* When it is a regular import, it should not import binary modules that
are built with -enable-testing, it should prefer interfaces if that is
available.
* When testable import, it should only load binary module and it should
make sure the internal imports from binary modules are actually
required for testable import to work.
If a testable import only find a regular binary module, dependency
scanner currently will just preceed with such module and leave the
diagnostics to swift-frontend, because the alternative (failed to find
module) can be confusing to users.
