Rename opentelemetry-instrumentation-api module to v1.14 and add v1_14 subpackage

[trask]

Part of #18428

Renames the directory to introduce a base version (opentelemetry-instrumentation-api-1.14, matching the muzzle floor of 1.14.0-alpha) and moves the javaagent classes into a v1_14 subpackage, bringing this module in line with the convention used by the other self-instrumentation modules (opentelemetry-extension-annotations-1.0, opentelemetry-instrumentation-annotations-1.16).

Pull request overview

This pull request renames the opentelemetry-instrumentation-api instrumentation module to a versioned directory (opentelemetry-instrumentation-api-1.14) and moves javaagent code into a v1_14 subpackage to align with the versioned-module conventions used by other self-instrumentation modules.

Changes:

• Updated Gradle settings and javaagent aggregation to depend on the new :instrumentation:opentelemetry-instrumentation-api:opentelemetry-instrumentation-api-1.14:* project paths.
• Introduced a dedicated testing subproject under the new versioned module, including an AgentSpanTesting helper and its bytecode instrumentation.
• Updated instrumentation-api javaagent sources/tests to the new io.opentelemetry.javaagent.instrumentation.instrumentationapi.v1_14 package and added an additional instrumentation module name alias.
