Hi,
what is high-level (P4) FPGA programming?
By google search, I found this:
https://www.netcope.com/en/products/p4-to-vhdl

Does it mean it is different from VHDL/Verilog? If so, is there any good book/material available for this?

Does one need different tools/compiler to work with P4? If so, what is it?

where this is used? Are all fpga/tools from Xilinx/Altera support this language?
 

It looks to me like P4 is A language for processing data packets, nothing more, nothing less. The link you provided describes a tool for converting P4 to VHDL.
 

Looks like a way to lock people into netcope's hardware. Not something that would be open to the public to use on their own hardware.

Basically a sales pitch disguised as a fashionable high level language.
 
A bit off topic...

If you are willing to program FPGAs without using VHDL/Verilog, like using C/C++, then have a look a Vivado HLS. It has its adv and disadv, depends on what type of development is intended. I have never used HLS.

The following info might be useful to you-
