Embassy for MSPM0

This adds an embassy hal for the Texas Instruments MSPM0 microcontroller series.

So far the GPIO and time drivers have been implemented. I have tested these drivers on the following parts:
- C1104
- L1306
- L2228
- G3507
- G3519

+# Examples for MSPM0L222x family
+
+Run individual examples with
+```
+cargo run --bin <module-name>
+```
+for example
+```
+cargo run --bin blinky
+```
+
+## Checklist before running examples
+A large number of the examples are written for the [LP-MSPM0L2228](https://www.ti.com/tool/LP-MSPM0L2228) board.
+
+You might need to adjust `.cargo/config.toml`, `Cargo.toml` and possibly update pin numbers or peripherals to match the specific MCU or board you are using.
+
+* [ ] Update .cargo/config.toml with the correct probe-rs command to use your specific MCU. For example for L2228 it should be `probe-rs run --chip MSPM0L2228`. (use `probe-rs chip list` to find your chip)
+* [ ] Update Cargo.toml to have the correct `embassy-mspm0` feature. For example for L2228 it should be `mspm0l2228`. Look in the `Cargo.toml` file of the `embassy-mspm0` project to find the correct feature flag for your chip.
+* [ ] If your board has a special clock or power configuration, make sure that it is set up appropriately.
+* [ ] If your board has different pin mapping, update any pin numbers or peripherals in the given example code to match your schematic
+
+If you are unsure, please drop by the Embassy Matrix chat for support, and let us know:
+
+* Which example you are trying to run
+* Which chip and board you are using
