renderer: more FP16 fixes (#14070)

* fix fp16 blur with invalidation

* restore tonemap code

* fix fade outs

* add sdr compat for unaware surfaces

* use a better work space, not linear, only for sdr

* fix hl tf -> wp tf

* cache workbuffer descriptions

* linear not normalised WIP

* clear offload fb

* CM math

* fix includes

* use precalculated cm for shadows

* inner glow cm

* quad cm

* fix unmodified copy

* codegen

* cache color CM

* mark blur dirty when CM/DS changes

* avoid icc workbuffer

* fp16 blur finish hack

* fix output hdr luminances

* use srgb for mirroring/sharing with fp16

* defaults people
