mesa: Fix computation of transform feedback num_components.
The function tfeedback_decl::num_components() was not correctly
accounting for transform feedback of whole arrays and gl_ClipDistance.
The bug was hard to notice in tests, because it only affected the
checks for MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS and
MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS.
This patch fixes the computation, and adds an assertion to verify
num_components() even when MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS
and MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS are not exceeded.
The assertion requires keeping track of components_so_far in
tfeedback_decl::store(); this will be useful in a future patch to fix
non-multiple-of-4-sized gl_ClipDistance.
