- HWC tonemapper passes secure flag to GPU tonemapper to create object
with secure EGL context.
- Tonemapper object gets created with secure EGL context for the tone
mapping of secure HDR layer.

Tone mapper engine setting the current eglContext and never
restored it. With multiple eglContexts used in same thread
by SurfaceFlinger and GPU Tonemapper, it lead to incorrect
eglContexts being used, hence always store the restore the
eglContext in each GPUTonemapper call.

- The fd's used for book-keeping can change when the clients
close and reopen sessions, hence they are not reliable and
can lead to incorrect virtual address usage causing
corruption or stale data.
- Hence use ion cookie for book-keeping which is unique for a
given memory fd.
- Use LRU method free up/reuse on reaching max limit.
- Remove Tonemapper_destroy which is not needed anymore.

- Use individual EGL contexts for each tone-mapping
session.
- Having one context make multiple sessions serial, this
helps in making this parallel when possible.
- Resolves error messages which happened when the context
was deleted during mirroring.

Need to switch to current egl context before deleting the
program other wise it leads to errors and may not clean up
cleanly on deletion.

Tonemapper does not clear the eglImage/fd mappings in the destructor,
which leads to incorrect usage of those fds, when a tone map session
gets deleted and a new session gets created, leading to artifcats.
