This reduces the amount of copies of the Runtime::block_on and related
functions the compiler has to generate and LLVM process. We've seen it
reduce the compilation time of our tests (some 1900 of them) from 40s
down to 12s, with no impact on the runtime of tests.

Below is an output of llvm-lines for our tests.

Note that I have replaced our test functions with XXX. As you can
clearly see they're not in the top 20 in the before output, while
they're in the after oput.

Further note that the amount of copies have been reduced from 156577 to
41634.

macros: reduce usage of last statement spans in proc-macros (#5092) 
This excludes the initial let statement of the proc-macro expansion
from receiving the last statement spans to aid completions in rust-analyzer.
The current span confuses rust-analyzer as it will map the tail expression
tokens to the let keyword (as this is the first token it finds with the
same span) which currently breaks completions. This commit should not
degrade the initial intent of the span reusages, as the type mismatch
parts are still spanned appropriately.

macros: forward input arguments in #[tokio::test] (#3691) 
Fixes #2388

Previously `#[tokio::test]` would error on functions that took
arguments. That meant other attribute macros couldn't do further
transformations on them. This changes that so arguments are forwarded as
is.

Whatever else might be included on the function is forwarded as well.
For example return type, generics, etc.

Worth noting that this is only for compatibility with other macros.
`#[test]`s that take arguments will still fail to compile.

A bit odd that [trybuild] tests don't fail `#[test]` functions with
arguments which is why the new tests are run with `t.pass(...)`. They do
actually fail if part of a real crate.

time: make test-util paused time fully deterministic (#3492) 
The time driver stores an Instant internally used as a "base" for future
time calculations. Since this is generated as the Runtime is being
constructed, it previously always happened before the user had a chance
to pause time. The fractional-millisecond variations in the timing
around the runtime construction and time pause cause tests running
entirely in paused time to be very slightly deterministic, with the time
driver advancing time by 1 millisecond more or less depending on how the
sub-millisecond components of the `Instant`s involved compared.

To avoid this, there is now a new option on `runtime::Builder` which
will create a `Runtime` with time "instantly" paused. This, along with a
small change to have the time driver use the provided clock as the
source for its start time allow totally deterministic tests with paused
time.
