egl/dri2: try to bind old context if bindContext failed

This change mostly touches error handling code paths, where a
bug was found when the DRI driver failed to bind a new DRI
context. Specifically, the reason for it to fail was the window
system unable (for whatever reason) to provide the DRI drawable
with a buffer. In this instance, Mesa un-does the EGL bindings,
but doesn't restore the old DRI context, hence remaining in a
funny state. It's worth mentioning that despite trying, there
is no guarantee that the old DRI context can be restored,
depending on the runtime.

Before this change, if bindContext() failed then
dri2_make_current() would rebind the old EGL context and
surfaces and return EGL_BAD_MATCH. However, it wouldn't rebind
the DRI context and surfaces, thus leaving it in an
inconsistent and unrecoverable state.

After this change, dri2_make_current() tries to bind the old
DRI context and surfaces when bindContext() failed. If unable
to do so, it leaves EGL and the DRI driver in a consistent
state, it reports an error and returns EGL_BAD_MATCH.

panfrost: Allocate syncobjs in panfrost_flush

For implementing panfrost_flush, it suffices to wait on only a single
syncobj, not an entire array of them. This lets us wait on it directly,
without coercing to/from syncfds in the middle (although some complexity
may be added later to support Android winsys).

Further, we should let the fence own the syncobj, tying together the
lifetimes and thus removing the connection between syncobjs and
batch_fence.

panfrost: Skip specifying in_syncs

With the current kernel UABI, there is no benefit to explicitly

that meant checking for CCS_E.  On Gen12, there are a lot more types
of compression, and basic CCS_E was replaced by GEN12_CCS_E, making
this check simply not work, so we'd take the CPU path instead.

Instead, check if it has CCS, and isn't the basic "fast clear" CCS_D.

nir/algebraic: optimize bcsel(a, 0, 1) to b2i

This avoids combination with other bcsel operations,
and as b2i is often a no-op (when used for iadd and such),
the resulting pattern is preferable.
