Certain define types don't work well when building assembler files

Type: Bug Report

Describe the bug

OS and Version: Windows 11 22H2 (Build 22621.963)
VS Code Version: v1.74.2
Extension Version: v0.10.0
Target Device: No particular device
Description: If defines are used that result in the following arguments during the build of *.s files, the build fails.
```
-Wa,armasm,--pd,"TEST SETS test"
```

To Reproduce Steps to reproduce the behavior:

Clone this repository https://github.com/RobertRostohar/Demo_EW/
Open the Blinky folder in VS Code
Open the Blinky.csolution.yml file for editing

Add following defines section to the Debug build type.

defines:
- DEBUG
- INIT_COUNT=2
- CONFIG_FILE=config/config.h

The build-types section should look like this:

build-types:
- type: Debug
  compiler: AC6
  defines:
    - DEBUG
    - INIT_COUNT=2
    - CONFIG_FILE=config/config.h
  misc:
  ...
- type: Release
  ...

Build the project with Target Type B-U585I-IOT02A and Build Type Debug

The build should fail with this assembler file:

\<path-to-repo\>/Blinky/Board/B-U585I-IOT02A/RTE/Device/STM32U585AIIx/startup_stm32u585xx.s

and print the following error message:

"<command line>", line 6 (column 18): Error: A1516E: Bad symbol 'config', not defined or external
    6 00000000 CONFIG_FILE SETS config/config.h

Expected behavior The build should not fail with assembler files and this kind of string like defines. When I edited the command line build of the mentioned assembler file:

\<path-to-repo\>/Blinky/Board/B-U585I-IOT02A/RTE/Device/STM32U585AIIx/startup_stm32u585xx.s

like this:

-Wa,armasm,--pd,"CONFIG_FILE SETS \"config/config.h\""

I was able to successfully build the whole project but I'm not sure if that would be the correct approach.
