The changes were mostly automatically applied using the following
Python script:
```python
import os, re
for root, _, files in os.walk("."):
for f in files:
if not f.endswith(".rs"):
continue
p = os.path.join(root, f)
with open(p, "r", encoding="utf-8") as file:
lines = file.readlines()
changed = False
for i in range(len(lines) - 1):
if re.search(r'#\[error\(".*: \{0[^}]*\}"\)\]', lines[i]) and "#[source]" in lines[i + 1].strip():
lines[i] = re.sub(r': \{0[^}]*\}"\)\]', '")]', lines[i])
changed = True
if changed:
with open(p, "w", encoding="utf-8") as file:
file.writelines(lines)
print("Fixed:", p)

error: lifetime flowing from input to output with different syntax can be confusing

This streamlines the code base to follow best practices for
error handling in Rust: Each error struct implements
std::error::Error (most due via thiserror::Error derive macro)
and sets its source accordingly.
This allows future work that nicely prints the error chains,
for example.
So far, the convention is that each error prints its
sub error as part of its Display::fmt() impl.

By introducing `imports_granularity="Module"` format strategy,
effectively groups imports from the same module into one line or block,
improving maintainability and readability.

Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

This removes the storage of the GuestMemoryMmap on the CpuManager
further allowing the decoupling of the CpuManager from the
MemoryManager.

We don't use the VmmOps trait directly for manipulating memory in the
core of the VMM as it's really designed for the MSHV crate to handle
instruction decoding. As I plan to make this trait MSHV specific to
allow reduced locking for MMIO and PIO handling when running on KVM this
use should be removed.

This commit adds event fds and the event handler to send/receive
requests and responses from the GDB thread. It also adds `--gdb` flag to
enable GDB stub feature.

This commit adds initial gdb.rs implementation for `Debuggable` trait to
describe a debuggable component. Some part of the trait bound
implementations is based on the crosvm GDB stub code [1].
