Since 1.75 std provides an interface to set access and modified times on files.
This change replaces the external dependency previously used for these operations
with the corresponding std functions.

Reason:
In order to build the Windows version of the Rust toolchain for the Android platform, the following patch to the cc is crate is required to avoid incorrectly determining that we are building with the Android NDK: 57853c4bf8
This patch is present in version 1.0.80 and newer versions of the cc crate. The rustc source distribution currently has 3 different versions of cc in the vendor directory, only one of which has the necessary fix.
We (the Android Rust toolchain) are currently maintaining local patches to upgrade the cc crate dependency versions, which we would like to upstream.
Furthermore, beyond the specific reason, the cc crate in bootstrap is currently pinned at an old version due to problems in the past when trying to update it. It is worthwhile to figure out and resolve these problems so we can keep the dependency up-to-date.
Other fixes:
As of cc v1.0.78, object files are prefixed with a 16-character hash.
Update src/bootstrap/src/core/build_steps/llvm.rs to account for this to
avoid failures when building libunwind and libcrt. Note that while the hash
prefix was introduced in v1.0.78, in order to determine the names of the
object files without scanning the directory, we rely on the compile_intermediates
method, which was introduced in cc v1.0.86
As of cc v1.0.86, compilation on MacOS uses the -mmacosx-version-min flag.
A long-standing bug in the CMake rules for compiler-rt causes compilation
to fail when this flag is specified. So we add a workaround to suppress this
flag.
Updating to cc v1.0.91 and newer requires fixes to bootstrap unit tests.
The unit tests use targets named "A", "B", etc., which fail a validation
check introduced in 1.0.91 of the cc crate.
This reverts commit 9267843e72, reversing
changes made to e52fbff5e8.
This breaks our ability to bump the src/version where we're bootstrapping with an older compiler
than usual (according to version number). It's not clear whether the intended use case has a clean
solution given this constraint, so reverting for now - we can reland with a fix of some kind implemented.
Update serde in workspace and non-synced dependencies
The main workspace, bootstrap, cargo, miri, and rust-analyzer all lock serde to different versions. It's preferable to share the same version where possible, so update it.
Rustfmt is synced from another repository and has its own Cargo.lock, but since it's added to the overall workspace it should respect the version here.
Cargo is already at the latest version. Miri and rust-analyzer would require upstream updates.
