Introduce adaptive sharpness

This new setting modulates sharpness based on frame QP, which helps
mitigate blocking artifacts in the low to medium quality range.

This can be enabled by parameter --enable-adaptive-sharpness=1, or
by using codec control AV1E_SET_ENABLE_ADAPTIVE_SHARPNESS.

Enabling adaptive sharpness comes with a very small (but measurable)
decrease of SSIMULACRA2 scores (Daala's subset1), so only enable by
default for AOM_TUNE_IQ.

rtc: Fixes/adjustments to dynamic resize

For resize_mode = 3 (dynamic): add flag to
disallow 3/4 down/up switch, and increase
the time window for switching down/up.
Keep this flag (one_half_only) on as default
for now.

This reduces resolution toggling observed
in some tests.

Also relax the conditions for entering
the resize logic: allow it for screen content
mode and for aq_mode enabled.

examples/inspect: use malloc/free

Instead of aom variants. This fixes a link error when using
-DBUILD_SHARED_LIBS=1 after:
d737ca3ebe exports_com: rm aom_{malloc,free}

aom_malloc and aom_free are internal functions. The standard library
functions are sufficient for this example.

Thanks to Dan Fandrich (dan at telarity) for pointing out the issue.

Allow file paths with 'weird' characters.

Currently, if e.g. AOM_CONFIG_DIR is set to a path with special
characters (such as +), the cmake build fails. This is because
MATCHES interprets the second string as a regex, which is invalid.

Since we only care about substring existance in these checks, rewrite to
using FIND. Unfortunately, I could not find a way to do this in a
single line, so changed to two lines.

This is specifically a problem for us when using Bazel to build aom
(with the help of rules_foreign_cc, so essentially wrapping cmake in
Bazel). Bazel uses + in resolved paths for external dependencies and
our build is currently failing with Nested *?+., Error in compile..

Misc improvements to aom_wb_read/write_uvlc()

Add function comments. Document that UINT32_MAX is invalid for uvlc().
Audit all calls to aom_rb_read_uvlc() and verify they handle the
UINT32_MAX return value as an error.

Simplify aom_wb_write_uvlc() by calling get_msb(). Assert that the input
is not UINT32_MAX.

Improve cpu-used 8 all intra

This change splits discount_color_cost RDO decision into its own
speed feature. It has been found that discount_color_cost causes
excessive file size inflation on natural content that benefits from
palette mode, resulting in a net BD-rate loss (mainly in the low to
medium-high quality range).

Disable discount_color_cost for all intra mode, and keep the
current behavior for realtime mode.

Additionally, tweak cpu-used 8 speed features for a better
speed/quality trade-off:

• hybrid_intra_pickmode 1 -> 2
• prune_palette_search_nonrd 0 -> 1
  These new settings help compensate the speed loss from disabling
  discount_color_cost, but with a minimal BD-Rate loss.

Approximate BD-Rate gains over discount_color_cost enabled, plus
original speed feature settings - cpu-used=8 (Daala's subset1):

• SSIMULACRA2 60: -4.73%
• SSIMULACRA2 70: -3.34%
• SSIMULACRA2 80: -1.52%
• SSIMULACRA2 90: +0.04%

Before and after encoding example (subset1: Lufthansa - QP 20):

cpu-used	Size (bytes)	Time (ms)
7	233238	362
8 (before)	359941	296

Updating moz.build files
Found 3 files added and 0 files removed.
Could not add third_party/aom/av1/common/riscv/highbd_convolve_rvv.c to the appropriate moz.build file
Could not add third_party/aom/av1/encoder/x86/av1_fwd_txfm2d_hwy_avx2.cc to the appropriate moz.build file
Could not add third_party/aom/test/bitwriter_buffer_test.cc to the appropriate moz.build file
This is a deficiency in ./mach vendor . Please review the affected files before committing.

We're going to continue processing the update; but we may fail because we couldn't handle these files. If we do succeed, you may want to add these files to the 'exclude' key in the moz.yaml file, so they are excluded from the source tree and ignored in the future.

All jobs completed, we found the following issues.

Known Issues:

• browser/components/sessionstore/test/browser.toml
  - test-windows11-64-24h2/opt-mochitest-browser-chrome-msix-6 (bTuNwM7tS_CM0vW_SAeBJw)

• browser/components/sessionstore/test/browser_background_tab_crash.js
  - test-windows11-64-24h2/opt-mochitest-browser-chrome-msix-6 (bTuNwM7tS_CM0vW_SAeBJw)

These failures may mean that the library update succeeded; you'll need to review
them yourself and decide. If there are lint failures, you will need to fix them in
a follow-up patch. (Or ignore the patch I made, and recreate it yourself with
./mach vendor media/libaom/moz.yaml.)

In either event, I have done all I can, so you will need to take it from here.
When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
