Improve cache hit rate in windows build (#15538)
### Description
1. Update /Zi to /Z7 in abseil project while using cache
2. Skip target_precompile_headers while using cache
### Motivation and Context
There're about 1/4 uncacheable calls in Windows GPU compilation with
cache.
```
Uncacheable calls: 441 / 1641 (26.87%)
Could not use precompiled header: 361 / 441 (81.86%)
Preprocessing failed: 1 / 441 ( 0.23%)
Unsupported compiler option: 79 / 441 (17.91%)
```

The root cause of `Unsupported compiler option` is that /Zi in Abseil
isn't updated to /Z7.
The root cause of `Could not use precompiled header` is the
`target_precompile_headers` creates cmake_pch.pch every time and it's
hash value is changed too.
### Result
It could reduce compilation time by another 20%.
For example:
It took 16m43 in CUDA training compilation on Windows.
It takes 13m32 after the change.

### N.B.
In winml project, it's using own target_precompile**d**_header
https://github.com/microsoft/onnxruntime/blob/main/cmake/precompiled_header.cmake.
Just let it be.
