This also removes the need to have a test for `-b` parameter in
trigger-test-builds.sh, because the TC scripts calling this can already
factor that in.
Testing script trigger so only do builds of common to verify
Fixes: #14483
Test-bot: skip
Build-bot: skip:all build:common
Clarifies the confusing builder.inc.sh / build-utils.sh distinction by
giving the scripts more appropriate names. Most build scripts should use
builder-full.inc.sh; some helper scripts can use builder-basic.inc.sh.
Documented in resources/build/README.md.
Renames:
* resources/build/builder.inc.sh to resources/build/builder-full.inc.sh
* resources/build/build-utils.sh to resources/build/builder-basic.inc.sh
Other changes:
* Moves Android-specific functions out of builder-basic.inc.sh and into
android/build.sh.
* Renames functions in builder-basic.inc.sh
More functions may be moved from builder-basic.inc.sh into utils.inc.sh
or other scripts in the future.
Fixes: #14065

* `builder_has_action` renamed to `builder_start_action`
* `builder_report` renamed to `builder_finish_action`
* `builder_has_action` created to be a silent test for the action
* Added reasonably comprehensive documentation.
The background reason for this is to test a fix to the web build, where
s.keyman.com resources were not being updated since we refactored the
build configurations (sadly, the build did not die when it should have).
