Fix dynamic mesh handling when queued rendering is enabled. Track whether a mesh build has already been queued so multiple partial Draw() calls do not enqueue duplicate builds for the same dynamic mesh. Reset the build state when a new dynamic mesh is acquired or its buffers are detached.

Summary
Fix dynamic mesh handling when queued rendering is enabled.
Changes
Track whether a mesh build has already been queued so multiple partial
Draw()calls do not enqueue duplicate builds for the same dynamic mesh.Reset the queued-build state when a new dynamic mesh is acquired or when
its buffers are detached.
Reason
A dynamic mesh could receive multiple partial
Draw()calls before thequeued build was processed. This could enqueue the same mesh build more
than once and lead to rendering corruption when multicore / queued
rendering was enabled.
Testing
Tested with queued rendering enabled in the HL2 x64 build. The previously
observed visual glitches no longer occur.
