[tests] Simplify CreateDllBuilder() and CreateApkBuilder() calls (#10373)

Fixes: #10372

This PR simplifies MSBuild integration test code by removing redundant
explicit directory parameters from `CreateDllBuilder()` and
`CreateApkBuilder()` calls where the default behavior already provides
the same result.

## Changes Made

The `BaseTest.CreateDllBuilder()` and `BaseTest.CreateApkBuilder()`
methods have default parameters that automatically use
`Path.Combine("temp", TestName)` when no directory is specified. Many
tests were explicitly passing this same path, making the code more
verbose than necessary.

**Before:**

    using (var b = CreateApkBuilder(Path.Combine("temp", TestName))) {
        // test code
    }

**After:**

    using (var b = CreateApkBuilder()) {
        // test code
    }
