new 95f32fd01 nsh: Decouple with CONFIG_FILE_STREAM
95f32fd01 is described below
commit 95f32fd018be7a66354942647d9e1c778ad5d488
Author: Huang Qi <[email protected]>
AuthorDate: Fri Feb 10 17:50:46 2023 +0800
nsh: Decouple with CONFIG_FILE_STREAM
Replace all fwrite/fread/fgets/... to write/read/...
Before:
```
text data bss dec hex filename
109827 601 6608 117036 1c92c nuttx/nuttx
```
After:
```
text data bss dec hex filename
108053 601 6608 115262 1c23e nuttx/nuttx
```
After with CONFIG_FILE_STREAM disabled:
```
text data bss dec hex filename
105667 601 6608 112876 1b8ec nuttx/nuttx
```
