Make all swift anon targets content based hashed

Summary:
TSIA

For the anon targets, we could not use `get_uses_experimental_content_based_path_hashing(ctx)` to determine whether we enable content based paths to them (as demonstrated in D86439116)

The reason is that the current setup of rolling out the feature is on a per app basis by adding a modifier to the app's target platform. The issue that brings is that any dependency that is built against the execution platform won't get that information, causing them to still have content based paths disabled. Then, when come to anon targets, if target A and target B both depends on anon target X, if A has content based path enabled and B has it disabled, this would cause an inconsistent state for target X, which leads to a duplicate entry in modulemap.json (https://www.internalfb.com/intern/diffing/?paste_number=2028864153), and hence causing build failures.

The solution, as described by the updated rollout plan: https://docs.google.com/document/d/1tS5CUQ8Xdpx6-hbsUx6NoGXd4VpuZu7FeXtXfHVGoRo/edit?tab=t.0, is that we will be a bit more aggressive in our rollout strategy and just enable content based path by default to the targets that are causing issues.

Fix incompatible target blocking generation

Summary:
This command `fbpython arvr/tools/buck/vsgo --vs2022 --no-open --mode_files arvr/apps/hsr/mode/vsgo_dev --generated_folder=C:\\open\\generated_projects //arvr/projects/hsr/...  //arvr/apps/hsr/demo/...  //arvr/apps/hsr/example/...  //arvr/apps/hsr/holodeck/...` is blocking hsr stable because a newly introduced incompatible target blocked the generation.

Properly handle this in vsgo

Add tags and cli args to CommandStart

Summary: Want to add tags to know if memory-tracker-enabled is set for lost builds. CLI args just nice to have, mostly for the UI, but is easy to add at the same time.

Linkers: correctly pass flags for $(ldflags-shared)

Summary: Apple platforms required a set of linker flags to be always present, so ensure `$(ldflags-shared)` macro that can be used in `cxx_genrule()` contains them.

Allow clippy::uninlined_format_args

Summary:
This lint is failing buck2-oss jobs on revisions that used to pass, I can repro it with codesync but not directly in the repo, despite the fact that codesync does not modify any relevant code.

It's unclear to me how a lint could be flaky, presumably it's not the lint itself, but in any case this doesn't seem useful and it's disabled elsewhere in the repo.

Make KIC default

Summary:
### Context
We are integrating the Kotlin Incremental Compiler (KSIC) into Buck to enable incremental compilation of Kotlin source files. This aims to enhance build speed by recompiling only modified source files within a target, rather than rebuilding the entire target.

### This diff
After testing on IG and WA, KIC will be the default option for all Kotlin targets.

*Note: This change will be announced by a public post before landing.*
