Provide a ${this.__name__} variable (like ${this.__env__} but valid in all sections)

Configuration

PlatformIO Version (platformio --version): 6.1.6

Description of problem

As stated in #4480 (comment), I am using ${this.__env__} to get the environment name in a non-environment section that will later be extended by an environment. This is being rejected as invalid (but it works) so I need the suggested ${this.__name__} to insert the name of the section/environment when the value is being evaluated.

[a]
test_testing_command =
	script.sh
	${platformio.build_dir}/${this.__name__}/test
	${platformio.build_dir}/${this.__name__}/program

[env:b]
extends = a

Where ${this.__name__} is expected to evaluate to b when the test_testing_command is used (this works with ${this.__env__} on 6.1.5).

[nomis]

I don't think ${this.__name__} is going to help because I don't want a or env:b, I need b which is the name of the environment. This is the only way to make a custom test_testing_command in a section that is not the final environment.

The ${this.__env__} variable is not returning the current environment being executed, but the environment name implied by the section name where the variable is accessed (which isn't necessarily the section where it's defined).

The only reason this works at all in older versions is because my section names are app:... extended by a single env:... so removing the first 4 characters happens to produce the current environment name.

[app:native_test]
extends = app:native
build_flags =
        ${app:native.build_flags}
        -DUNITY_INCLUDE_PRINT_FORMATTED
test_build_src = true
test_testing_command =
        app/pio/testing-command.sh
        ${platformio.build_dir}/${this.__env__}/test
        ${platformio.build_dir}/${this.__env__}/program

[app:native_test_coverage]
extends = app:native_test
build_flags =
        ${app:native_test.build_flags}
        -fprofile-arcs -ftest-coverage -lgcov --coverage

[env:native_test]
extends = app:native_test

[env:native_test_coverage]
extends = app:native_test_coverage

With v6.1.5, ${this.__env__} is being evaluated as native_test and native_test_coverage because the section names are app:native_test and app:native_test_coverage, even though test_testing_command which uses ${this.__env__} isn't defined in app:native_test_coverage!

This would be a lot easier if the testing command was executed with PIO environment variables (including the program name).
