[clang][deps][modules] Allocate input file paths lazily (#114457)
This PR builds on top of #113984 and attempts to avoid allocating input
file paths eagerly. Instead, the `InputFileInfo` type used by
`ASTReader` now only holds `StringRef`s that point into the PCM file
buffer, and the full input file paths get resolved on demand.
The dependency scanner makes use of this in a bit of a roundabout way:
`ModuleDeps` now only holds (an owning copy of) the short unresolved
input file paths, which get resolved lazily. This can be a big win, I'm
seeing up to a 5% speedup.

[clang][deps] Collect discovered module dependencies' Link Libraries (#93588)
This will allow scanner clients to be able to compute e.g. auto-linking
dependencies of the scanned translation unit.

[clang][deps] Always generate module paths
Since D129389 (and downstream PR https://github.com/apple/llvm-project/pull/4965), the dependency scanner is responsible for generating full command-lines, including the modules paths. This patch removes the flag that was making this an opt-in behavior in clang-scan-deps.

[clang][deps] Stop sharing FileManager across module builds in scanner
Sharing the FileManager across implicit module builds currently leaks
paths looked up in an importer into the built module itse
[clang][deps] Stop sharing FileManager across module builds in scanner
Sharing the FileManager across implicit module builds currently leaks
paths looked up in an importer into the built module itself. This can
cause non-deterministic results across scans. It is especially bad for
modules since the path can be saved into the pcm file itself, leading to
stateful behaviour if the cache is shared.
This should not impact the number of real filesystem accesses in the
scanner, since it is already caching in the
DependencyScanningWorkerFilesystem.
Note: this change does not affect whether or not the FileManager is
shared across TUs in the scanner, which is a separate issue.
