TODO: docs

squash this into the commit that first added all_tests.ts, we don't even
want to have a trace of it left

for the cli ones, we can simply iterate the filesystem relative our
location. for the web one, we determine it on launch and expose it as an
endpoint from the server which the client queries

+Subject: drm/amd/display: Reduce number of arguments of dcn30's
+ CalculateWatermarksAndDRAMSpeedChangeSupport()
+
+CalculateWatermarksAndDRAMSpeedChangeSupport() has a large number of
+parameters, which must be passed on the stack. Most of the parameters
+between the two callsites are the same, so they can be accessed through
+the existing mode_lib pointer, instead of being passed as explicit
+arguments. Doing this reduces the stack size of
+dml30_ModeSupportAndSystemConfigurationFull() from 1912 bytes to 1840
+bytes building for x86_64 with clang-22, helping stay under the 2048
+byte limit for display_mode_vba_30.c.
+
+Additionally, now that there is a pointer to mode_lib->vba available,
+use 'v' consistently throughout the entire function.
