app/vmagent/common: use plain sync.Pool instead of a mix of sync.Pool with channel-based pool for PushCtx
This scheme was used for reducing memory usage when vmagent runs on a machine with big number of CPU cores
and the ingestion rate isn't too big. The scheme with channel-based pool could reduce memory usage,
since it minimizes the number of PushCtx structs in the pool in this case.

Performance tests didn't reveal significant difference in memory usage under both low and high ingestion rate
between plain sync.Pool and the current hybrid scheme, so replace the scheme with plain sync.Pool in order
to simplify the code.

all: use clear() built-in Go function for clearing []prompbmarshal.TimeSeries and []prompbmarshal.Label slices
This makes the code a bit clear.

b8083b7659 lib/promscrape: clean references to label name and label value strings after applying per-target relabeling
This should reduce memory usage when per-target relabeling creates big number of temporary labels
with long names and/or values.
