Gerrit Timmer 4d57c52ab6 Free decoder frame caches and plane pools when an export ends (#3637) ...

Every source keeps up to 384 MiB of decoded frames plus its live decoders
for the whole session, and the 1 GiB process budget only trims caches that
were idle while another cache asks for frames. The 8/16-bit plane shelves
(192 MiB each) were never trimmed. A long-lived process (MCP) therefore
held 2-3 GiB after an export and ran out of memory on the second one.

Add filmcraft_codecs::release_idle(), which empties every cache nobody is
decoding on (try-locked, so users are untouched), and
filmcraft_frame::pool::trim_planes(). A standalone export calls both next
to trim_f32 when its pipeline drops; parts of a batch keep them.
