encoding/json/jsontext: preserve buffer capacity in Decoder.Reset
The Decoder.Reset method is not preserving the internal buffer between
resets, causing buffer capacity to be lost and resulting in unnecessary
allocations when reusing decoders. This is particularly problematic when
decoding many small messages.
This commit fixes the Reset method to preserve the internal buffer. It
makes sure aliasing is removed if the buffer currently points to an
internal byte slice of a bytes.Buffer. It adds a TestDecoderReset test
structured into subtests to better validate the different scenarios.
