Resolves Gradle deprecation and language version warnings
```gradle
Java compiler version 21 has deprecated support for compiling with source/target version 8.
```
The `java.toolchain.languageVersion` syntax is a superset that covers the previous syntax `android.compileOptions`
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.

Adds documentation for various functions, removes unused functions (a
couple of simple, very lightly used functions were unDRYed; these could
go back the other way across all shell scripts if necessary). TODO items
noted for follow-up refactoring.

Also set `RELEASE_OEM` and `RELEASE_OEM_FIRSTVOICES` at build time (if
`--fv` is passed) instead of relying it to be set in TC.
Fixes: #14350

`--ci` is deprecated since the current code discovers automatically
when we're building on CI, so we don't have to pass that option when
calling the `android/build.sh` script.
Also remove the option itself since we're no longer using it.

To facilitate code investigation and issue repro attempts, we should log the
engine's current keyboard, language code, and model when reporting errors.
Fixes: KEYMAN-ANDROID-71V
(As this adds Sentry logging, I needed a reliable error with inspectable logs
for development.)

PR #13854 missed (at least) one place when renaming the variables from `TIER` to `KEYMAN_TIER`. This change fixes the release builds for Android.

Previously the builder scripts defined a readonly `VERSION` environment
variable for the Keyman version. That caused problems when another
(external) script tried to define a `VERSION` variable. We encountered
this problem when trying to move the TC build steps of a configuration
into a single script (#13399) when we tried to source `~/.nvm/nvm.sh`.
This change uses a Keyman specific prefix for the version variables and
renames `VERSION` → `KEYMAN_VERSION` etc. Unfortunately these variables
are used in a lot of places, so this turned out to be a bit of a yak
shave.

If a keyboard package is missing associated languages, show an error dialog instead of Toast notification., This way we don't clutter Sentry with noise.
