compilers: Don't use -I=path in TI toolchains

[gpollo]

Meson currently uses the syntax -I=path instead of -Ipath when using Texas Instruments compilers.

This is problematic because it generates a compile_commands.json using this syntax and tools such as clangd will fail to use the compile_commands.json.

Now, I tried checking if there was TI compilers that only supported -I=path syntax and I couldn't find any. I checked TI CGT, TI MSP430 and TI C2000 compilers, which were the compilers that were initially supported by Meson. I also did a deep research with Gemini and it couldn't find a TI compiler that required -I=path and even discouraged it (not perfect tools, to take with a grain of salt).

Additional Changes

I've found out that the same can be said of --define=foo. It should be -Dfoo.

@gpollo can you link to online documentation for these three compilers?

@bonzini I linked documentation on most TI compilers found here.

Additional Tests

I've a made a simple Docker image that installs all TI compilers from this page and tested them using -Ipath and also -Dkey=value (rather than -D=key=value, also Meson's current behavior) and they work.

Inside the container, I used this script to test the arguments and they all worked.
