mesa: skip validation of legality of size/type queries for format queries

The size/type query is always legal (if we made it that far).
Removing this causes a difference for GL_TEXTURE_BUFFER - the reason is that
these parameters are valid only with GetTexLevelParameter() if gl 3.1 is
supported, but not if only ARB_texture_buffer_object is supported.
However, while the spec says that these queries return "the same information
as querying GetTexLevelParameter" I believe we're not expected to return just
zeros here. By definition, these pnames are always valid (unlike for the
GetTexLevelParameter() function which would return an error without GL 3.1).
The spec is a bit inconsistent there and open to interpretation - while
mentioning the "same information as querying GetTexLevelParameter" is
returned, it also mentions that 0 is returned for size/type if the
target/format is not supported - implying correct results to be returned
if it is supported, regardless that GetTexLevelParameter would return
an error. (Also, the bit about this returning the same as
GetTexLevelParameter also includes querying stencil type, which isn't
even possible with GetTexLevelParameter.)

This breaks some piglit arb_internalformat_query2 tests (which I believe to
be wrong).

The code just considered all formats as being supported if they were either
a valid fbo or texture format.
This was quite awkward since then the query would return "supported" for
e.g. GL_RGB9E5 or compressed formats and target RENDERBUFFER (albeit the driver
could still refuse it in theory). However, when then querying for instance the
internalformat sizes, it would just return 0 (due to the checks being more
strict there).
It was also a problem for texture buffer targets, which have a more restricted
list of formats which are allowed (and again, it would return supported but
then querying sizes would return 0).
So only take validation of formats into account which make sense for a given
target.
Can also toss out some special checks for rgb9e5 later, since we'd never get
there if it wasn't supported in the first place.

Testing for gles there is just confusing - this is about target being

nir: partially revert c2acf97fcc9b32e

c2acf97fcc9b32e changed the use of double_inputs_read to be
inconsitent with its previous meaning. Here we re-enable the
gather info code that was removed as the modified code from
c2acf97fcc9b32e now uses the double_inputs member rather than
double_inputs_read.

This change allows us to use double_inputs_read with gallium
drivers without impacting double_inputs which is used by i965.

We also make use of the compiler option vs_inputs_dual_locations
to allow for the difference in behaviour between drivers that handle
vs inputs as taking up two locations for doubles, versus those that
treat them as taking a single location.

mesa/vbo: replace vbo_draw_method() with _mesa_set_drawing_arrays()

The arrays specified by ctx->Array._DrawArrays are used for all
vertex drawing via vbo_context::draw_prims().  Different arrays are
used for immediate mode, vertex arrays, display lists, etc.  Changing
from one to another requires updating derived/driver array state.

Before, we indirectly specifid the arrays with the gl_draw_method values.
Now we just directly specify the arrays instead.  This is simpler and
will allow a subsequent display list optimization.

In the future, it might make sense to get rid of ctx->Array._DrawArrays
entirely and just pass the arrays as another parameter to
