Use lane-referencing intrinsics in Neon convolution kernels
The Neon convolution helper functions take a pointer to a filter and
load the 8 values into a single Neon register. For some reason,
filter values 3 and 4 are then duplicated into their own separate
registers.
This patch modifies these helper functions so that they access filter
values 3 and 4 via the lane-referencing versions of the various Neon
multiply instructions. This reduces register pressure and tidies up
the source code quite a bit.

Remove references to deprecated NumPy type aliases
This change replaces references to a number of deprecated NumPy type
aliases (np.bool, np.int, np.float, np.complex, np.object, np.str)
with their recommended replacement
(bool, int, float, complex, object, str).
NumPy 1.24 drops the deprecated aliases
so we must remove uses before updating NumPy.

vp9/rate_ctrl_rtc: Improve get cyclic refresh data
A client of the vp9 rate controller needs to know whether the
segmentation is enabled and the size of delta_q. It is also nicer to
know the size of map. This CL changes the interface to achieve these.

For --best quality, resulting function
vpx_highbd_fdct32x32_rd_neon takes 0.27% of cpu time in
profiling, vs 6.27% for the sum of scalar functions:
vpx_fdct32, vpx_fdct32.constprop.0, vpx_fdct32x32_rd_c for rd.
For --rt quality, the function takes 0.19% vs 4.57% for the scalar
version.
Overall, this improves encoding time by ~6% compared for highbd
for --best and ~9% for --rt.
[NEON] Optimize and homogenize Butterfly DCT functions
Provide a set of commonly used Butterfly DCT functions for use in
DCT 4x4, 8x8, 16x16, 32x32 functions. These are provided in various
forms, using vqrdmulh_s16/vqrdmulh_s32 for _fast variants, which
unfortunately are only usable in pass1 of most DCTs, as they do not
provide the necessary precision in pass2.
This gave a performance gain ranging from 5% to 15% in 16x16 case.
Also, for 32x32, the loads were rearranged, along with the butterfly
optimizations, this gave 10% gain in 32x32_rd function.
This refactoring was necessary to allow easier porting of highbd
32x32 functions -follows this patchset.

Rely on libvpx's decision to catch overshoot/undershoot and recode frames.
Previously, when external max frame size is set, we didn't handle
undershoot cases, and now we fall back to libvpx's decision to
recode a frame if overshoot/undershoot is seen.
